These were the same manifolds as used on the optional 355 hp(first hp per ci in an American car in spite of Chevrolet's 1957 claim of that feat) 300 B engine. I have a set for my car(thanks to Henry Nigg, who now tells me that he wants to buy them back), but one of them has a crack and I need to find someone to weld it properly. John Lazenby has a set on his 300 B. His B sounds great. They are the same as the Dodge truck. You can recognize them by the fact that they have 4 bolts to attach them to the exhaust head pipe. Also this pipe is of larger diameter then the 340 hp standard 300 B engine head pipe.
