Ok....this won't be started on until next winter but I want to hear some input on this. Im going to take a 75' 360 and stroke it to a 401, i'd like to go 10:1 compression along with the crank rods and pistons from Bulltear in the stroker crank kits being talked about. Hopefully using stock bore but i haven't gone into the engine yet. Im not to familiar with certain terms but mill the block and deck the heads to get the CR up and as far as having to run high octane petrol, i'd be more than happy to just to have a badass motor to show my die hard chevy brother up and make him go wimpering into the cornor :mrgreen: . I'd be using 3216090-1 heads fully port and polished with the works and Harland-Sharp roller rockers and Crane valve springs. Edelbrock Torker intake gasket matched and polished with a 850 double pumper Holley. Not sure yet on camshaft....but have a few ideas floating around. Full ARP bolts and stud kits for entire motor. Milodon 8 qt. pan, wet sump of course, maybe a stud girdle to go with the crank scraper.Gear to gear timing setup from Milodon? Front pump cover from Bulltear with hydro relief idler gear, remote dual oil filters with oil cooler. Edelbrock shorty headers, high flow alum. water pump. DUI dist with Livewires, MSD 6AL module. I've named all of what i have planned for right now but if theres any thing i left out feel free to reply and flame if you must. Any input will be helpfull good or bad.

Yes the $8000+ you need for all the suff and machining :? #-o
Unless you are really going to pumping out the power or turning super fast you can leave out the stud girdle and the Gear to gear timing setup from Milodon, Save the money and put into the heads and intake and headers.
P.S. DON'T buy Headman headers...they fit like crap. :(:

You don't say what you'll be using it for. Daily driver, towing, rock crawling, drag racing? Each will have it's own unique requirements. I've found over the years that the best spent money on AMCs is for balancing and head work.
Spend the money where it will do the most good. The Milodon gear drive is very noisy. Some "wow" factor, but you'll get the same performance from a quality roller set, and have around $400 to spend elsewhere if you count machining.

I've got hedmann's and they fit better than expected 8) had more room to work than with the stock manifolds and downpipes. I even got around lifting the engine on one side by removing the steering shaft. my only complaint is they gave me the wrong bolts and the flanges might be a little thin

This motor would be going into a 80' CJ-5 with a T-18 trans and Dana 20 transfer (soon to be Dana 300) with AMC 20 rear with superior axles, detriot locker, disc brakes and 3.73 R&P. Dana 30 upfront with superior axles and a detriot and some sort of truss. 4 inch Superlift springs still being spring-under to minimize axle wrappage. All while rolling on 35/12.5/15 Mickey Thompson Baja Claws with 32 bolt beadlocks. This Jeep would be an everyday driver that get takin on the weekend adventures while still driving me to school and work throughout the week.

For your application I would S--tcan the Torker manifold and 850 carb and look for a good dual plane and a 650-700. I doubt you are gonna want to sit in that thing at much over 80MPH so I would be looking for all the bottom end torque I could get.
Your target compression ration may also be a bit high for daily driver use on pump gas - try closer to 9:1. High rpm (in excess of 5000) is not necessary here either so stud girdles, gear timing sets, and such are a waste of money. Dont think I would use a crank scraper either.
You really don't need to go with ARP studs everywhere either, but if you do be sure to have the crank bore align honed with the main studs and have the block bored with a torque plate and head studs as well (they don't stretch as much as stock bolts and therefore result in different deformation).
Check out Thorley Tri-Y headers.

Buy some aftermarket heads. IMHO and from what I have learned, is to spend some cash there.

Tonight i finally finished the install of my 304 into the CJ and got her running. It's been a summer long engine build thats yielded a whole new chapter in my book for engines. This was my first AMC build and i was a bit skeptical wether to tackle her or not and im glad i did! Damn did it sound good sittin there purring smooth as a kitten. :mrgreen: :!:
gschuld
Congratulations on firing up the 304. Hope she'll run great for you. The 304 that you just spent a lot of time, effort, and money on was built for the same 1980 cj that you were just talking about building a monstor high winding stroker 360(401cu in) for? If that is the case, why not just keep it in there for a while at least until everything else is done. I'm not sure if you have more than one jeep project going, but weren't you looking for a whole different body tub for it as well. By your posts, it sounds like you don't have the rest of the drivetrain ready for massive 401 power yet. I'm not trying to give you a hard time here just want to help you out. As mentioned above, the stroker you first described would be a VERY expensive proposition. Seriously even if you do all the assembly yourself, the parts, machining, and balancing for everything needed to put it together and STAY together would cost upwards of 6 grand, probably closer to 8. It ads up REAL quick...I've been there. Unless you intend to go after FUZZ401s 1/4 mile record in his cj7(somewhere in the 12.4 range with 37 super swampers!) I would seriously reconsider your strategy. A great big pile of torque from off idle to about 4500-5000 is where the vast majority of cj guys want...and for good reason. You can do it with 9 to 9.5:1 comp and ported iron heads, much more comp. and you run the serious risk of needing race gas to keep out of detonation meltdown. I've run a 69 Firebird with a 383 chevy built in similar fashion to what you were talking about and not only is race gas expensive, but it is not available about anywhere but a race track. I ended up buying it by the drum and basically had my own filling station at the house. It's frustrating to say the least. Certainly for a daily driver to school, etc. I have a 360 in my 79CJ5, nothing fancy, just a stock rebuild bottom end with an edelbrock performer package(timing chain, cam, springs, intake, etc) The eddy cam isn't far from stock specs either. Free flow manifolds, 600 holley, basic stuff. Tremec 150 trans, dana 20, dana 44 rear, dana 30, front with 4.10s, 3in. spring lift with BFG 33/12.5/15s. The thing runs great. Far better than the stock 304 I ran earlier. The lifted 5's are so unstable as it is. Please keep that in mind. Lots of power in a tall, narrow, top heavy jeep can make it very dificult to even get all that power to the ground.
Your 401 build would potentially double the power of my 360...maybe more! That hurts my brain just thinking about it.
Keep in mind that a nice strong 401 could be built using off the shelf parts that would most likely make you happier in the end that would cost you far less than half both in money and time than your full tilt mill. I have a feeling that if you took a ride in a cj with nicely biult "off the shelf parts" 401 like I mentioned, you would be quite satisfied with it and would not feel the need for even more power.
If your serious about going the all out direction, read about FUZZ401's CJ7...he is one of the few out there that has really gone that route you are exploring, and lived to tell the tale.
As far as the other stuff, give me a call, I'm the one with the complete CJ5 fiberglass body. I have rears, lifted springs, gas tanks(21 gallon and stockers), 401 stuff, t-18, dana 20s, about everything really.

Well my plan is to snag up a 84? Scrambler my buddy has. Its got a I-6 with a TF999 auto and D300 but it also has $5500 into Currie 9in.'s front and rear with ARB's. Daytona yellow with half cab and good body and great frame! He purchased about 4 years ago b/c he couldn't pass up the deal for 5k. But im planning on getting it here sometime this summer. So the stroked 360 was going to be a project for that beast. But as far as going through with it right away........im gonna get soem ideas and amass the parts and kind of stockpile them into a year long build. But as far as the CJ-5 goes.....when i get her on the road here after a few weeks i'll have about 8k into it. I started off with pretty much a body frame and bare rearends and built from there. I drove the Jeep all summer with a wore out 350, chevy 4spd and 205 and had a 13inch!!! rear shaft and was tired of changing u-joints in the damn thing. So i tore it down mid-fall and started to rebuild. But i see that you mentioned you have gas tanks....i have a stock 20 or so plastic one in my jeep but it has a bad sending unit....i have no idea where to find one since all parts stores have a listing for just the 13 gallon one :(: but i'd be more than happy to hear more about what all 401 parts you have :mrgreen: Oh and by the way my names Nick but everyone calls me DuNgA hense the last name.......Paglialunga but where are you located? Im in S.E. Ohio right on the borden of W.Va
gschuld
DuNgA hugh...works for me. I'm in Toms River, New Jersey. It would be much easier if everyong just filled out their profile when registering on this forum. Is keeping that secret a good thing...no one seems to fill out the location part. Oh well!
I've got lots of parts. Enough to assemble a late 70's cj from scratch...with parts left over. V-8 radiators, 2 extra sets of t-150/dana 20s, narrow dana 44 with 3.73s, 3 worn 304's, 2 or 3 extra stock gas tanks, an aftermarket think walled 21 gallon tank, th400/quadratrac with matching driveshafts for cj7, 15x10in. steel rims, enough 401 blocks, cranks, rods, heads to build 3 of them, 291c heads, intakes...2bbl. 4bbl. performer, R4Bs Complete fresh 1968 390. Full cj5 fiberglass body, 79 cj5(with title) rolling chassis with perfect condition frame, lots of stuff.
After looking at your post in the pictures section, I had assumed that since the cj5 was the only jeep you had after selling the 7, that was going to be the intended jeep for the killer stroker 360. And we all know what happens when we assume... A scrambler would be much more capable of using lots of power. Longer wheelbase...big help!
To get an idea of the kind of motor(401) that I was talking about do a google search for (impersonator 406) you will find a sbc 406 done up by a chevy magazine. Lots of torque in 400 cubes. Similar power could easily be accomplished with off the shelf parts for a 401. If you already need to find a 401 crank and rods for your stroker, I'd suggest just locating a 401 block while your at it. It will probably save you money in the end. Plus the end result will likely be more valuable if it is a true 401 block motor. It really isn't very difficult finding a great deal on 401 stuff. Or maybe I'm just lucky. A good junk yard scored 401 would make you smile for weeks.

I run a constant 12.7 on 37" but going to try a set of 33x10.50 slicks to see if I can get down to the low 12's
I have a friend that lives in toms river in NJ has a pair of SS AMX's
I just dont under stand why people think I am nut 111!!! for running the jeep at the drag's :-| :-| :-| :-|

Hmm...george. That rolling chassis and fiber tub is sounding pretty good rite about now. How much would you ant for the chassis, glass tub and frt. clip, 401 and them 291c heads, and misc parts enough to assemble a roadworthy 79 CJ-5. I've always liked the 5's for some reason but soft tops suck! I'm thinkin i need to get my debt paid off here beginning of summer and i might just have to take a trip on out to Jersey and see wutcha got. The more i think about it the more i want another CJ. These things are like an obsession to me hahaah :?: I've had 7 CJ's so far and one Cherokee and im only 19! All but 2 were everyday drivers. Oh and the important thing i need most is a transmission belly pan thingy....that damn P.I.T.A. crossmember. What im doing is taking a T-18 from a 76' CJ-7 and puttin the 304 and T-18 into the 80' CJ-5. So far its all gravy except the crossmember that was on the 5 was butchered so far beyond use and the one from the 76' is different since it was an open C channel frame and its way differnet. Im planning on making one if i cant find one cheap but the strage thing is the only ones i can find are older ones and one from a CJ-6!!! 111!!! Talk about a goofy looking Jeep but also very neat in its own way :!:
DuNgA!

The 76-79 and 80-up CJ skid pans are different, but the frames are the same. Either one should bolt up to the 80 frame. I have a modified 80-up skid on my 77. Bolted right up to the frame. We had to modify it because it wasn't designed to clear the drop of a T-18. I also use a Scout Dana 300, which is clocked much higher than a Jeep 300, so I was able to eliminate the low spot in the skid under the t-case.

Well im not exactly sure what this came off of too. I bought a CJ-7 that had an 84 title but the original title sticker said it was a 76'. I decoded the vin from the 76' and it said it came with a 304 3 speed but it had a T-18 in it when i bought it. So im not too sure what its from. But one thing is that it deff will not fit. Not even if i redrill, it's just too different.

FUZZ401...Oh I heard about you! George has mentioned you on a few occasions! He and I have been doing a bit of trading lately. Two things come to mind...I'm extremely impressed and you must be out of your freaking mind! Mid 12s in a lifted 7 with 37 super swampers! Somehow I doubt 37in mud tires have been "speed rated" for 110+mph! Someday I must get out there and see your Kamikazee runs for myself. I have no idea how you keep a straight line at the end of the track. Hats off to you...and keep you life insurance updated just in case. I wrote a goofy short story in the amcforum's kill stories section that would give you an idea as to the extent of my entire "racing career" with a lifted CJ.
76 cj7...
Man just give me a call. There is just too many factors to do this by forum snail mail. I'll try to make it worth your while. Some thing I'm just not interested in letting go. The 291c's are one of them, and it has nothing to do with money. Plus they don't flow any better than the 58cc heads anyway...most agree that actually don't flow as well. The reasons that they are considered desirable to most people are 1-they were only made for about one year and 2- if you are running an otherwise perfectly stock low compression motor that is in good shape and you don't want to take it apart, replacing the stock 58cc heads with 291c(51cc) heads would bring up the compression up nearly a full point. I have 3 sets of perfectly good 58cc heads, cleaned, magnafluxed, and with new thinwalled bronze valve guides installed(by a pro).
I have atleast 2 spare 76-79 tranny/transfer case "belly pans". All were from factory v-8 CJs.
Well you sure have a head start on the lifetime volume CJ ownership record. How many...7..8....and your 19. You sure have me beat...and I'm not jealous. Is this some sort of A.D.D. for cars, they must have some form of counseling available for that! ....Just kidding. Well there sure are worse addictions. Come to think of it I bought my first at 19...in fact that is the same 5 with the great frame that I was talking about. It's been "retired" and put inside some 4 years ago now(it has been kept inside for much longer though). Kept it because it was my first and favorite and I had some good adventures(memories) with it.
I guess it's time to let it go. Maybe I should get some counseling!

Oh and as far as the soft top thing. You might be amused to know that for the first 3 years of owning the CJ-5(when I was young, cheap, and totally nuts) I ran some old "fastback style" soft top that came with it that just draped over the roll bar and snapped around the back and sides. Basically it was a top with no doors or windows by design. I ran it that way all winter long(in New Jersey) as my sole daily driver. I learned to really appreciate the insulating powers of a Carhart full potato suit. Two layers of fleece hats, some thick ski gloves, thermals...and for some reason I seemed to love every minute of it. I made it a habit of taking the canvas off everytime it snowed...just more entertaining that way. The jeep has never had anything but that ratty top on it since I bought it. After a few years, I simply got a daily driver for the bad weather days.
When I bought the 76 cj-5 I run now I bought a Besttop Supertop. It's far from cheap, but it sure is a nice top. I don't know of anything that even comes close.

George well the 37 are retired for the street only now I have 33x10.5 slicks on it so it is a little lower to the ground now :mrgreen: best was 102.5 mph so I am ok for the 110 range :mrgreen:
fuzz401
good story mine on the street can get like that but at the track it is as stright as a arrow the only place it gets funny is after the traps if I let off the gas to fast the locker unlocks and I can feel it get funny for a sec and thats it
