Match Race '67' Dart 273 Commando vs. Rambler American 290
Cudavert,
That Carter #4252 AFB is correct,,,,,,,625 CFM
1 7/16" Primary x 1 11/16" Secondary........with 1.062" x 1.562" Venturi Sizes
It had 'one-size' smaller jets installed at the Factory, but still a 'Thirsty Rambler'. -------------------------------------------------------------------------------------------
Also, the Cast Iron Dual-Plane Medium-Riser Intake Manifold
Had a good Runner Port Design, but was one heavy bastard.
