    OK....you can always get a decent feel for where you are from here...
    The complete bolt on list....
    Your probably around 300 RWHP as so much depends on the tune and compression/ring pack efficiencies etc....but I'll stick with 300 RWHP +/- 10%...1/4 mile....you should be able to get mid to low 13's with a decent launch....lot of assumptions here....
    This is my signature. It is mine. Nobody else has one like it.

    I would say you might be somewhere around 315-330 RWHP and 330-340 RWTQ. Just a guess though. And a low 13 (13.0-13.4) quarter mile with street tires, high 12 (12.8-12.9) with ETs.

    On an M6 02 w/ headers, lid and exhaust I would say in the 340rwhp range. I have seen plenty of cars similarly equipped with good drivers go high 12's w/ street radials. Low 13's even with a bad driver.

    no way a stock z28 makes 310 at the wheels, even if its manual. stock manual ss's usually only make 300-305. he'd be lucky if his car made 295 stock, definately not 310.

    the SS and Z/28 make just about the same horsepower, maybe a 5 h.p difference max.

    I've seen four different stock 2001-02 F-bodys on two different dynos. The average was around 308 (with one non-WS6 T/A hitting 319), so I gave him the benefit of the doubt on 2rwhp. SS/Z28/WS6/T/A/Formula...they all make the same base numbers unless they have SLP options. Regardless, you can use 300rwhp if you want.
