Title: 1 piece rear main block
Post by: 76_Scottsdale on March 03, 2008, 11:27:25 pm

Will a 1 piece rear main block bolt right up to a two piece blocks motor mounts and accessories as in swap right in?

i'm assuming you are talking small blocks(i know jack about big blocks). i believe everything is the same. the only thing that changes is the flywheel.

K once piece blocks are externally balanced correct? I'm looking at crate motors and they offer both i was just thinking the one piece because of ease of changing the seal. They're 383 strokers so I'll have to change the flywheel anyways.

They are still Gen I blocks so everthing will mount the same, the flexplate won't be the same.

i'm glad someone knew. i have been looking through my motor building books for an answer to the balancing question.
