      t4 60-1 upto t70. all depends on cam, heads, rpm, and boost.

      Several of us making that power and more with Precision PT-52's. I chose them because they are relatively small and great quality.

      If you want a somewhat specific answer gonna need a LOT more details than that.

      Heads? Cam? 408, 427, 436? want a 8500 rpm screamer or keep it somewhat tame? auto or manual trans? what standalone efi are you using?

      making 1k rw on pump gas will be interesting, and I almost have to ask why for a street car? that is a TON of power. 750 and it will be a much more reliable car, so much more enjoyable to drive, and will still make you piss your pants when it spins the tires at 90mph.

      Huge amount of info and experience on this question at ls1tech.com, in their 'forced induction' forum.
