331 With turbo runs hot

I ask about the intake gasket because I had the junk non-S Felpro cause me some problems in one of my turbo cars. Once I switched out to the "S" gaskets with the metal core my problems went away.

I don't know much about your particular fan but in the past I had issues with aftermarket electric fans. The OEM fans like the SN-95 are great. They do pull some amps tho.

The dual Spal fans on my Ron Davis work well.... but at a cost.
