A street engine should run ice cold compared to a race engine...Relatively speaking. I try to have .090 walls to start with on a 3 3/8 +.030 bore.
I ran 315 ci engines on the street many times and never had cooling problems....The big thing is to have the block acid stripped so you have bare metal to start with in the water jackets...Rust and scale are great insulators. A radiator that is clean inside helps too.
