'1967 Holiday Race' ~ Plymouth GTX 440 vs. Pontiac GTO 400 'Ram Air'

Wow! I wonder how much time Jere Stahl spent dialing that carb combo in. Staggered jetting, etc....I would imagine that would be out the window as soon as you swapped intake manifolds or maybe even exhaust. It's hard to argue with his results back then!

I believe that for the Drag Test for Super Stock and Drag Illustrated, the only
upgrade to the 'Carter AFB' #4327S was changing the Primary Jets from .098"
to .101".

Just a little 'richening' of the Air-Fuel Mixture.
