Looking for a Mark IV crank and pistons. Block is 0.040" and needs to be bored larger.
Will go up to 0.060"-0.070" Might consider rotating assembly. Re-building a Merc 420

Thanks

I have a GM std/std forged crank. $395 plus shipping.

800XC where are you located? I might have a line on one locally, but just in case.

Crank is in central WI

I have a gen 5 454mag with 25 hours on it for sale, probably for less than you can rebuild yours for

also gave a gen 6 454 mag short block that just needs some rings and bearings. Also have some 454 truck short blocks cheap. Gen 6 as well
