I'd go more around 9:1, you should hit 675rwhp easily with an 88-91mm turbo or twins.

i vote for 9:1 no problem with that size turbo and motor.Probably make that on by12-14 psi.9:1 wont be as sluggish when your foot is not in it

9:1 with that power.
Also take a look at an ST80 with an A/R of 1.1 that will spool at i want to guess 2500 prob less? and will easly make 675 @ the wheels.

Goodluck!

+1 on the 9:0. Under a 454 is noticeably sluggish at 8:1. Should be a fun build!
