with a 4.500 stroke it will be 572. no chain and gear that i know of must use a belt drive or a gear drive, also been said before check the main studs make shure they are ARP and not just the nuts, i recently bought a Alum version and going thru the same thing. but i'm going 4.750 stroke.

Raised cam block allows clearance for the 4.75" stroke , last motor i had used a 4.562 bore with a 4.625 crank , was 604ci , the 4.562 bore that uses the 4.750 crank nets a 622ci.

Here is a formula

Bore X Bore X Stroke X 8 X .7854 = CI

4.5 x 4.5 x 4.625 x 8 x.7854 = 588CI

4.5 x 4.5 x 4.75 x 8 x.7854 = 604CI

4.562 x 4.562 x 4.750 x .7854 x 8 = 622"

Randy

will be 604, think the biggest you can go with cast blocks is 654, 4.560 bore and 5.00 stroke can get more if you can go 4.600 bore.
