.040 over on amc 258?

i just pulled the head off of the 258 i was planning on rebuilding and found that it has been bored over .030. What is the max a 248 can be bored over?

1. If you need to go .060 over...
2. The block's had it...
3. Or, bore and sleeve the bore (not recommended).

Re: .040 over on amc 258?

Kevin,

Congrats on getting your first Jeep - it's a great milestone for you! If, as I suspect, the "86" in your name is your yr of birth, I was also about the same age when I got my first Jeep - a '66 CJ-5. What a learning experience. Hope your '83 is in better shape than my '66 was!

Anyhow, if you decide you want/need another block to rebuild, let me know. Thre're not too expensive around these parts and I might even have an extra one (for rebuild purposes) I could part with.

Where in eastern VA are you?

Re: .040 over on amc 258?

Thanks, yes you are correct, i am 17. I live in Williamsburg. My jeep is in great condition, (except for the engine). It has no rust, factory paint w/ renegade decals, and brand new tires. I am about to go mic the bores to see if they are worn considerably. If i need a rebuildable block i will consider you as an option, how close are you to williamsburg?

I have never worked with the 258 but my parts book shows .060 over pistons so I would assume that you can safely bore .060 over. (Leve do you know a secret???)

Kevin,

You're a lucky young man... my first Jeep was a 'rougher than a cob' rust bucket. (But, as a positive the rust issues did give me a chance to use some body work skills and rebuild an old relationship w/ a former employer.)

I am about 2 hours from you - W on 64, hang a right on 95 and go north about 60mi.

What tranny do you have... I've got a supposedly good running 258 w/ a TF(?)999 attached to it - never been apart. Bought it off an Army sgt in MD who swapped a 4.3 into his 83 or 84 CJ-7... As Leve is wont to suggest, 'Never hurts to have a spare [insert part of choice] standing by.' [Or sumthin close to that! [img]images/graemlins/grin.gif[/img])

Let me know if I can do anything for you... Not a real experienced Jeep hand yet, but learning more and more from the sages of this board as time passes. Hint: Stay close to this board... amazing the amount of good info that flows through on a daily basis. "Ask and ye shall receive!" Do not fear to ask questions (after doing a reasonably diligent search), we all learn from one another. There are No stupid questions... but sometimes the answers can get kinda....?????

Godspeed in your project!

Re: .040 over on amc 258?

Thank you MarineOpLaw. I am pretty sure that the trans i have is a Warner t-4. i believe that the t-4 trans is what they used for a 4 speed in the 83's but i might be mistaken. As for the engine that you have that runs, i am more interested in buying a block, or a bad engine w/ a good rebuildable/boreable block. I might not need anything, as i have all the parts from 2 engines, and a block that will most likely clean up by going .040 over. thanks-kevin

If your trans has a curved shifter it's a T-4, if it is straight it's a T-176.
