I was concerned about the rod ratio and piston size in a low deck stroker, didn't realize that a conventional BBC has a lower deck height than a B block. That's good info. The Bill Mitchell and Callies blocks aren't available in low deck but that's great to know the Indy is. Thanks!

Even if I did a 540 or 572 I'd only expect it to make 700-ish with the smaller headers and a 4150 style intake, and then hope to spray 200-300 on top of that. It would be neutered on motor for sure. The only benefits I can see with that route is the block should live at the 900 hp level on nitrous forever. I don't think a stock block will.

Custom headers are definitely an option, but at that point I'd honestly consider going turbo instead. Nitrous I'd leave it carbureted, but if it got a procharger or a turbo I'd definitely bite the bullet and go EFI. There are too many advantages to it, especially if I had to buy a larger or different carburetor and new fuel pump anyway.

Thanks guys. And definitely need to work on getting weight out of the car...
