Yes, in 1969 the 383 A-Body's had 335 HP engines but were rated at 330 HP because of the restrictive drivers side manifold. The 440 was still rated at 375 HP in an A-Body...
Thank You Sir! So they all had the "Roadrunner" cam, and 906 heads. Man those cars were bad! They'd scoot a B body along pretty good, I can only imagine what they do in one of them! YEE HAWWW!
