Re: Casting #s/ ID/ 4.0 block
Thanks again Jaffer...
I didn't realize that the block would have changed for '94/95. That block should work as well, do you know the casting number(s) for it?
I am going to end up having the block over bored .030 (since it is used), getting custom pistons, 4.0 rods (weight balanced), 4.2 crank for a 4.6 stroker engine.
This is the result of a piston or piston ring failing in my block. The block had passed compression tests with flying colors prior to the 4.0 head swap. I am guessing that all of the add'l power caused a weak link to go. The block was a reman. block with about 20K miles. I understand the company who reman'd the block (Bonded) went out of business due to so many warranty returns.
