That's the compression ratio Ross comes up with so your old timer was dead on! http://www.rosspistons.com/calculator.php
As far as the 402 goes, It may not the the most "optimal" set-up to max out a T-4 turbo, but it will still make some sick power on pump gas. I’m also willing to bet it does not have a much back pressure (which is obviously the concern running a larger CI motor with a T-4 turbo) than some of the less efficient single turbo kits running on 346’s.
I’d much rather have a PTS kit on my 402, than an old TTI or QMP kit on my 346. IMO it will be a good set-up and make nasty power on pump gas.

where did you pick up your 76gts and if you dont mind how much did you pay for it? im in the same boat (sorta) as you. im looking for a great all around turbo that will make around 700rwhp or better on either race gas or pump and alky. i was planning on around 20psi or so for high boost. i was originally planning on a t67 or a t70 but a local supra guy ran the 76gts with GREAT success (10.0's@140) so i want to check into it...
*EDIT* but im also working on a strict budget as well.

Hell yeah I want 'em, I was gonna send you a PM last night (but I passed out instead ) about them...
Mine is so close to the street that I DARE NOT SPEAK OF PROJECTED TIMING Alas, I have been seriously downtrodden and scorned by the Mighty God of Turbo Delay. I see you have appeased him; I'm working on it.
