I'm running a small block with the long water pump and accesories in my 68. It was originally a big block truck and the fan is exactly where it was with the big block and I have a good 2 1/2 inches of clearance from fan to radiator even with a 2 inch spacer and a stainless flex fan. I NEVER overheat or even come close to it. It all depends on where your motor mounts put the engine. My motor sits farther back in the engine compartment than other original eqpt 67-72 small block equipped trucks I have seen. I am using the big block motor and tranny mounts and frame mounts with the original close ratio NP 4 spd transmission and 4 core big block/AC radiator.
