I do believe that to be correct Tim. When I was shopping and studying what cam to put into my 235 car engine, I was informed to use a 60 something 261 cam, mechanical lifters and I'd have the same valve breathing as a 1954 Corvette. If I had the Corvette 3 carb intake and the Corvette split exhaust I would have a 150-155 HP engine. I have only a single Rochester Stock carb and Split Fenton exhaust headers with straight pipes all the way out to a bit behind the rear bumper . It gives me a smooth idling engine that sound and goes like a raped ape when I put my foot thru the carb. I can only dream how it would sound and accelerate with 3 side draft ? carbs feeding the 6 cylinders.
