Stroking the 4.0
I have a 4.2 crank that has already been turned. I also have the pistons
(.030 over) that were going to go into my CJ8. Question is; will the
pistons that I have for the 4.2 work in a 4.0 block provided the block is
bored to match the pistons?
Thanks

Re: Stroking the 4.0
Hi Chris,
I don't think so, the 4.2 liter has a stock bore of 3.75" plus your
..030" would still be smaller than the 4.0L's 3.875" stock pistons.

Re: Stroking the 4.0
Keep the 4.2 con rods, they're shorter than the 4.0 con rods by .250 or so
IIRC... don't want to mash your valves!
Verify this before taking my word on it.
