Hurricane .100 oversized HELP!

I started rebuilding my 58 CJ-5 recently. I planned to freshen up the motor which smoked a bit with a valve job and new rings.Pulled the motor apart to find that it has been bored out .100 over. Too expensive to resleeve and haven't been able to find rings that big.

Any ideas?

 

Another useable block is going to be by far the cheapest solution. There may be enough meat left for boring larger, but once you get into custom pistons and rings, the sleeves will look cheap.

 

Mine also had .010 over pistons. I just redid it with .020s and we carefully field em down and gapped 'em. Runs great, once warmed up there is no blow by except at highest revs.

 

OH my bad you're at .100 not .010, wow never mind!!!!!!!

 

Modern gray iron blocks are finished at 60 over; selected blocks can sometimes go more than that. Older engines used more iron, and 80 and 100 over likely was ok for these engines. Walcks has 80-over pistons for these ... I would call them and ask them about larger sizes.

I recall that sleeves are about $100 per hole. Not terrible, since there are only 4 holes...

If you can find a block that's in good condition (no cracks) nearby, it will be cheaper. Finding one will be the trick.

 

58HalfCab, your probably not far away from me.
I don't have any more spare F-heads but.....
There a guy down in the Burnes Mill area.
I think he's parting out a nonrunning 3B.

 

I'm driving one on my place that is .080 over and it runs a little on the warm side, but never fails to start. I was going to re-sleeve it, but I finally just put in the .080 pistons.

At this point in the process, sleeving the block is no big deal -- costs a few $$, but that beats searching out another engine and discovering that it has a new set of problems.

I think that the thing that would put me over the edge on this engine is the crankshaft. If the crank has been milled too far then, a new crankshaft along with the .100 cylinders would make me search out another engine. But if it is only the .100 cylinders that is the problem then re-sleeving should work fine.

However, I do have 4 spare F heads sitting around. One is locked up tight, but the other three could be good -- never really checked them out.
