1967 ~ Barracuda 383-S and Dart GTS-383 ~ 280 HP 'How can this be.'

Have you ever looked at the cast iron manifolds on those A-body motors? Especially the drivers side. Its a wonder they made 280. Ditch em for headers and hello 325plus!

And dont overlook the torque; 400/2400 rating versus the 340s what 340/3200? Are you kidding? 400/2400! Thats fun.
