360 vs 383
So I have a factory 360 roller cam from a ramcharger in a 69 Barracuda and a 69 Dart GT with a warmed up 400. I have never had the chance to race myself. Both cars make about 425hp and the torque developes at the bottom end for the big block and at the top end for the small block. Both have 3.55 gears and a converter designed for the engine. The small block has bigger tires because of the bigger wheel wells, the big block uses 14" vs 15" which effectively raises the ratio in comparison. The small block leaves the line better but the big block finishes way better. You decide.
