What type of internals would I need if I were running high boost regularly (15-20psi) and what would be the limits if I did runs even more than that?
I've heard that people use the stock crank for 1000hp+ in Brazil so a machined stock crank should be fine right? I know forged steel stuff is what I need so forged rods with ARP bolts should be what I need right? Lastly, the only pistons I can find are cast aluminum. Do pistons need to be strong? I'm not sure if that's a stupid question but I know they aren't subjected to rapidly changing angles, just up and down motion. So would cast aluminum be ok for high performance applications?
It should be about $600 for internals so that's not that bad.
69 Buick Special Deluxe. Intercooled Turbo Chevy 250 @ 15psi on a stock long block. It's kinda fast.
