I'm sorry that this is not in response to your question but I have a 97 and in Virginia too and was wondering about a couple of things in your sig. How did you like the head swap? I assume you did the intake too. Did you get a lot from it? And finally do you like the 3.73s or do you wish you did the 4.10s?
i havent yet did the headswap myself, but i know that you can use the bigger comp cams modular cams (278ah's) which should drastically increase performance. i think the mm&ff got over 400fwhp outa some ported PI heads, these cams, and miscellaneous other things on a stock 98 2v short block. ide research different cams as a next mod, b/c they'd be a great compliment to the better flowing heads.
In the May 2004 issue of MM&FF the had Tech article titled Partoit Games II(page 126). The car they used for it was Their Own "Project Ice Box" A 2001 GT with a Vortech SQ S/C with aftercooler, ported Bullitt intake, BBK/SLP exhaust, Superchips performance, 3.73's and a Steeda Suspension. In previous tests the car laid down 400rwhp and 12's at 118mph in the 1/4 with no traction. In part II, they added a set of Ported PI heads by Partoit, along with Comp Cams Xtreme Energy .545" lift 234/238 dur. cams and a set of JDM 1 5/8 LT headers. The results were 540rwhp@ 6,200 and 470 '#'s of torque@ 5,200.
A buddy of mine just put a set of PI heads on his Vortech s trim 01 GT . I havn't talked to him in about a week and as far as I know he hasn't had time to get it dyno tuned yet, so I'm not sure what kind of #'s he's putting out now. I'll call him tomorrow and find out what's going on with it and I'll post back.
before the headswap i was very satisfied with 3.73, but after the headswap i wish i had 4.10. The headswap really opened up the car. Much better acceleration and defiantely more torque. Love the "new ride" A must do.
