Sheesh, had to wade through a lot of Chevy BS to find all the Mopars! What do you think yours puts out? I would think 500 pounds of TQ should be real feasible with a 408, considering you can do it with a mild 440.......
It had me thinking, if these guys and their ported j head 410, 950 carb& LD manifold only made that much, how much does mine make?
And how good or poor was there port job? I know the cam was small lift wise and not as fast of a profile/ramp...
They post no head flow #'s so I'll never know what they really had.
