Hy Guys, to my eyes that is a modified GMC engine, probably started with a 270 and modified from there. That cylinder head is definately a GMC, and NOT a Chevy (no scallops around the head bolts). As for the manifolds, could be Clifford 6 = 8 research, or some other aftermarket company. Definately a modified GMC engine to me.
