Thread: How do you make a big block run cool?

Tweet

Thanks for all your input.....I will be making a few changes.....restrictor instead of thermostat......I have an aluminum shroud that came with another radiator, and I think I can do a little fabrication to make it fit this one. I guess I will just accept the fact that this motor is never going to run as cool as what I'm accustomed to with small block Chevys. To answer some of your questions, Pat.....I run 40 degrees of timing.....some will say is a bit much, but that is where it runs. The CSR water pump is pumping normally, but I have thought about switching to a mechanical pump to see the difference. The car has no blower, turbo, etc.
