Re: Boiling over.......

Most SBCs specified a 195 thermostat. Haven't tested it myself but several folks claim that running no thermostat degrades cooling because the coolant moves too fast through the radiator. Maybe too much speed causes turbulence that limits heat transfer.

If that is a flex fan, add a stock 7 blade fan to your list.

Might research doing a switch to electric fans. May be cheaper then obtaining the proper parts to restore the OEM cooling setup.
