Truck 383 Different than car 383?

StrokerScamp said
There WAS an early 383 truck engine that was a raised deck engine similar to a 440. Other than those, they are all pretty much the same regarding cores.

Thanks StrokerScamp. By "early 383" do you mean the '58-60 RB 383, or a different year?

pretty much the same expect the exhaust manifolds.

Thanks mopar7172. Can you tell me how the manifolds are different, and whether you think the truck manifolds would work better than the car manifolds in an early A?
