i recently purchased my first classic car and my first pontiac: a 1970 lemans 2 door with the factory, numbers matching 400 engine, 4 barrel quadrajet and th400.

i haven't been able to drive it because i'm fixing some mechanical problems.  just curious though.  the only mods it has are 1-5/8" hooker long tubes, and 2-1/2" dual exhaust with xpipe and spintech mufflers.  what kind of power will it make at the wheels, given the th400.

i believe pontiac originally rated the engine at 330.
