Most GM Bowtie blocks can be bored to 4.630", and I have seen 4.750" stroke cranks fit, but be prepared to do a whole lot of rod clearancing. Most of the Mountain Motor IHRA style aftremarket Blocks, have a 5.000" bore center spacing that allows a much larger bore, 4.750" is pretty easy to obtain, and usually 800 cubic inch is normal in the P/S classes.

I need to correct myself. Sonny Leonard currently has a 932 Cubic Inch GM style engine. It has a 5.300" bore spacing and has a 5.080" bore with a 5.750" Stroke for a mere $89,300 dollars. It has 2140 HP and 1475 Ft. lbs. of torque!

Only $90,000! We should all go out and pick one up today at those bargain basement prices.

It's worth noting that this is NA- expect that those engines get 3-4 stages, to boot!

A 572 is already bored and stroked about as far as you can go. Aftermarket blocks can easily go into the low 600s, but you'll be well into the $40,000 range to get it until you buy the block, custom pistons, crank, oil pan, timing chain, valvetrain components, and heads that will supply enough air. Not to mention the $10,000 on a tranny that will take the torque, $10,000 on a rear axle, a full cage that won't twist the car in half.... the list is endless.

It entirely depends on the block and how thick it is to start with. On a production 454 block (which were all short deck), I've seen 526 (60-over with 4.5 stroke) but it all depends on the block. Some can be safely overbored more, and some can be clearanced a bit more for a crank before hitting water.
