1968 '340' Barracuda vs 1968 '383' Road Runner

I bought a pure stock 68 FB formula S B'Cuda, 340, auto, 3:23 open, had 145k on it when i purchased it from orig. owner. I was driving a 68 RR, 383, w/ headers otherwise pure stock, 4 spd, 3;23 open, at the time. While I never lined them up, I feel the fish was faster. Also lets remember that the 68 4 spd 340 cars had a hotter camshaft/dual point dist. then the following years. I think a 68 340, 4 spd coupe cuda or dart, with a factory part numbered, LD intake, headers and 3:91 gears would have been a formidable package!
