61mm or 70mm turbo?

I recently purchased a turbo kit that came with a t61 turbo, but I also have a 70mm master power sitting in the shop. I was wondering would be the best choice for my 331 stroker. It is probably going to have some forged reverse dome pistons and some other decent interals. I'd like to make around that 450 rwhp. Was just curious what turbo would be the best and around what psi I'll have to run to make my goal.

Shew! If you only want 450HP ... I'd for sure go with the 61! Quick spool and it'll EASILY support that power without suffocating.

Depending on specs a cast wheel 61 will choke a 331 cube motor. It would support about 450rwhp on a 4.6L fine.

Depends on the rest of your setup. If you are auto I would go 70. If your a manual and stock block, go with the smaller one. Also depends on if you want a all out drag car, or fun street car.
