More info on the intake and carb setup please. Did you make adapters for the 2g carbs? What carbs did it have originally? Is that a factory manifold for a dump truck or aftermarket? Thank you.
Intake is a factory dual one barrel intake. They came on the 354 Power Giant engines in dump trucks, fire trucks and other medium duty applications. I found the adapters at Summit by Trans Dapt. Carburetors are the big 2GC GM two barrels.
