Thanks for the add into the group first. So I have a 1956 gmc truck with a370 c.i. Pontiac engine. I’m interested in putting a 1965 389 ci 4 barrel manifold and carb on it. From my research it seems the 370 and 389 are the same block. My worry is the 9 years separating them and if I’ll run into any problems involving the cooling system. Thanks in advance for any help
