Inliners International Forums General Discussion Hi Performance New Guy Here. 68 Camaro with an L6 250.

I am wondering how is the 68 Camaro almost 1second faster then me bone stock when I have a turbo 350 and he has a powerglide? Do you have the68 engine rated at gross hp and me at net hp? Do my bumpers slow me down that much? Please don't think that I am complaining , I think that the Gonkulator is great thing. If possible please explain. Thanks in advance, Jay 6155
