After switching out the TFI thinking it was a ignition problem I found out the BAD news (on the wife's CJ) is that I did a compression check & here's what I found.
Cylinders:
1. 145lbs
2. 140lbs
3. 65 lbs*
4. 145 lbs
5. 150lbs
6. 140 lbs
I think that's why it's running kind of rough.
I asked her if she wanted a 360 dropped in that puppie but she said she like's her 6, (women).

Well I drove the Jeep to work today & it ran excellent/smooth, then I got about 8 miles from work & I heard a TING,,,,,clack, clack, clack & then it was very rough running. I made it back home & tore it down but I ran into a problem & had to stop. I don't have a torques bit to get the dipstick tube off of the head so tomorrow I'm gonna buy one.
Keep U posted,

P.S. I ran it after I pulled off the valve cover & the rocker/springs on the head look fine, none broken.

Well, I found the head gasket next to the #3 cyl. had a small hole in the h2o jacket which leaked into the #3 cyl. The water blew a small hole in the piston & it scored the top of the cyl wall. I have a spare engine that I though waas junk but come to find out it has been rebuilt per the previous owner so I'm gonna install that one & hold my breath.
I'll get back w/U all on the out come.

P.S. Saturday is the dig day, here we go again.
P.S.S. The jacket rusted through, that's why it happened. :(:

Well installed the other engine & everything sems to be working fine. It's a 1982; 258. The head bolts are smaller & the intake & exhaust are different by a small amount. The rear main seal is different also so if U ever get a 1982; 258 make sure U specify with great specificity when buying parts.
If I were a 258 owner I would pull the head & replace the gasket if U haven't done it due to the fact when I pulled the 82's head I had 3 places where the head gasket rusted & it could have caused the samething to happen (blown piston). A friend of mine @ work had a 82' CJ8 & the #3 cyl did the samething, go figure. Cheap insurance plus U get a new intake & exhaust gasket job done also. lol

P.S. Thanks for all the help.

Cool beans Jim :t:
I swapped a 79 for an 87 258 and found some other issues, the mounts cast into the block were different (or non-existant!!)
Glad things worked out. Now rebuild the one you got for a spare. .030 over, crossed drilled and ground crank, port match and polish ... you know the drill :?

Ya Pat, I was thinking about removing the 360 & putting in the 258 (gas etc.). Hummmmmmm.
How much H.P. & torque would I gain if I did this;
1. Went 20 over?
2. went 30 over?
3. Installed the 4bbl intake/carb on her old 258?

You'll get LOTS with 30 over, balance, and a Webber 36 or 38. I think a 4bbl would be too much unless it was a small one?? You'll alos get a lot with a port polish on the head. Smooth the exhaust all the way in and just hit the hi spots and remove the flashing on the intake. Erin's 258 is way strong for a 6 and that's using hte stock intake and exhaust. I'm going wait on the additional HP (intak and headers/Webber) after she gets used to what she has. Mine is a BEAST with all of it installed. Stong on the low end - but gas milage leaves a lot to be desired :oops:

Thanks Pat, is there anyway to come up w/numbers for the 20 & 30 over scenario?
Can I use a stock cam to keep the miliage or do I have to change to @ least a RV cam?
Thanks,

Well it was a seat-of-the-pants dyno in Erin's and she has a new stock cam. I can try desktop dyno and see, but I don't have it on the laptop here in Charleston :smile:
