MY 401 Machining & Parts List (Parts Pics Added)

82Waggy

Thought I would post this up as it is fairly complete and may help others organize their engine projects. Note that this build incorporates the Edelbrock MPEFI kit wich includes a distributor, fuel pump, and other items not listed seperately below. I laid the list out in an Excel spreadsheet with costs (not included below) to keep track of everything. Below the list of parts is my finished Blueprint specs.

Current status is that all block related machine work is done and I am now waiting on head work to be finished up. Once heads are done I will need to aquire the last 2200 worth of the parts on the list to finish up - so get ready MC cuz most of those remaining parts will be coming from you!

[quote=Blown7]You forgot PIC'S!!!!!!!!!!!!!!!!!!!! I can't read so well but I like pretty pics of parts. Jeff[/quote] Ya, OK. I just set up a pic server so I'll start posting pics soon. Wish we could post direct so I don't have to try and manage so many sites. Ain't there no way to do that here?

82Waggy

BTW, I also had my 390 machine work done at the same time. What a financial mistake that was. I always seem to bite off more than I really want to chew at the same time. For now the 390 is on hold until I get my Jeep runnin.

Here's some pics! Table of Goodies. That's my 390 block freshly machined and bagged at the left end.

That's my 82Waggy chassis behind the block, freshly stripped and painted - waiting to put on 4" springs and install new gears with a Power Lok diff in the back before I paint the suspension stuff.

No bushing oiling holes used - they just show the rod where to crack! :shock: [img]http://i142.photobucket.com/albums/r107/82Waggy/401/KBBUSHNG.jpg[/img]

:lo1l: I like the EFI !!! Good choice to bring the engine into the 21 st century. Jeff

very nice indeed. i too am building a pro flo 401. i just got done tearing the old girl down, and have already purchased my mpefi (pace), thats actually how i found your post, someone directed me to your post because i was looking for a build list, wah lah, here i am. Thats truly a impressive list, what type of numbers are u trying to achieve? i am trying to reign in about 400 ponies and even more in torque. im still researching different options/combos. what were u going for, as far as usage? street, offroad, both, leaning further one way than the other? i look forward to hearing how yours turns out and any imfo. you might share. until then good luck. thankyou, wayne 76 chief [email]crownedclown68@msn.com[/email]

buy a ring filer for the top rings you will need a .027 ring gap

Somewhere in the forum is a dyno sheet for a 401 that made over 420 ft bs at 3400 and about 350hp at around 4400, as I recall. This engine used a comp X260 cam, a 670 Holley carb, performer manifold, Edelbrock heads, and about 9:1cr with speed pro pistons. I'm doing some extensive work on stock AMC 090 head castings, using a cam with a little more lift and tighter hydraulic intensity that should grind out some additional torque, the MPEFI of course, and probably a little better quench than the dyno motor. Should make at least the same if not slightly better numbers. I'm shooting for best torque at a lower rpm and do not expect much over 350 peak hp. Just received my Rollmaster timing set today and have everything else I need on the way from Bulltear to finish the engine. Tranny and Txfr case are done. Also have my 4" lift kit, new diff gears, and other miscellaneous stuff on the way from BJ's to finish the chassis - and the body man is finally hard at work. Should be running in July, knock on wood. Now I just need to pick a body color and get on with it.

Very nice plan. That would be me with the dyno'd 401. It is in a 89 GW and I am very pleased with the performance. I actually have another 401 at the machine shop now with the KB pistons and AMC steel heads with some work being done. I thiink it will make more power and torque than the last bulld with the stock pistons and Eddy heads. Where did you get "Pan Gasket, 1pc Rubber SCE?" Did not know you could get a one piece pan gasket for an AMC.

Please educate the un-washed (me) ... what is "CHS"

Oh YEAH... Looking good!

Here's the latest: [img]http://i142.photobucket.com/albums/r107/82Waggy/401/sblk.jpg[/img] Managed to misunderstand the timing marks on the Rollmaster and installed it a few teeth off. It has 4 advanced and 4 retard settings, requiring that you choose an appropriate crank keyway and then match the appropriate unmarked tooth to the timing mark on the cam sprocket. Trying to get a 108 centerline and the Rollmaster indexing sheet sucks. Recognized it was wrong and now have to pull it off again.

I don't beleive the listing I ordered it from - we'll see what actually arrives. Update 05/19/07: Nope. 1pc pan gasket not available. Got SCE 4pc set.

[quote=Mudrat]Please educate the un-washed (me) ... what is "CHS"[/quote] I listed some of the vendors by accident - the result of copy and paste from an Excel spreadsheet. CHS = "The Cylinder Head Shop & CHS Racing Engines", the machine shop I use and that I have been moonlighting at.
