VBelt pulley layout

I’d replace that with a Milodon high flow unit. They are relatively inexpensive and way better than that. You should also buy a QUALITY high flow thermostat. Stewart Components has the best one IMO. Make sure the water pump is turning faster than the crank.

BTW, there is no reason to ever run a thermostat hotter than 190. A 180 is better. Running hot coolant temps is a mistake many guys make. When you do that, you have to reduce the compression ratio to keep out of detonation and that is a power loser.

Don’t know what intake manifold you are using but I’d block the heat crossover off if it already isn’t. That’s another compression dropping detonation maker.

Thank you very much. Very helpful.
They are relatively inexpensive. I'll get that with the 180 stat.
