Thread: Can't shed the heat after going up steep hills? Run a little hot. More capacity? SBC

Yeah, I would fatten up the mixture first. Then I'd be looking at the fan. Is it an 18", 7-blade design steel fan like was used OEM? Are you using a fan clutch? Is the fan turning at least 1.2 times crank speed? Is there sufficient space for hot air to exit the engine compartment?

On the off chance that you're using an Edelbrock, here's the Owner's Manual so you can figure out the tune....

No I am not using a fan clutch. Fan is bolted to the waterpump with a spacer.
I can measure the waterpump pulley diameter and let you know.

The fan is a stock type steel fan. I will check how many blades it has. I remember it saying front on one side of the fan last time it was off.

I don't think I have vacuum advance. I will check. I have HEI but I am not sure on the advance. It will look just like a typical vacuum advance by the distributor like a Ford 302 right?
