4bbl intake for 318
Correct J-Par
The 'OP' has an all stock 1973 Dart 318 with an MSD-6AL and Dual-Exhaust.
He's not going anywhere in a hurry.
He's just looking for a little kick in performance.
His question concerning Intake Manifolds, was between an
Edelbrock 318 Streetmaster and a 1971 340 Cast Iron unit.
With plans of mounting a Holley 600 'Square Bore' Carburetor
on the Intake of choice.
If he can pick up a Streetmaster 318 for $100, that is a fair price.
