It has an emblem right in the front 370 and I have a title for it it’s a 1956 GMC one and a half ton truck I know Oldsmobile never made a 370 from my understanding the 370 block was the precursor to the 389 they just bored and stroked it correct me if I’m wrong I don’t know that’s why am on her asking questions thank you for your reply

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
