My 528 made 829 @6500. I'm still fighting the cooling problem. It's good for about 20-30 mins. on the road. idling it can sit for 30 mins or so easy. I have a Ron Davis radiator in it (26ins), 2 12in. Spal fans, ,160 degree thermostat mech. waterpump, 5 & 5 1/4in pulleys still Runs warmer than I'd like.

WATER PUMP PULLEY SHOULD BE SMALLER THAN THE CRANK PULLEY , AN 1 1/4 OR 1 1/2'' , 2 CORE RADIATOR , BIGGEST UNCAN FIT IN THERE WILL OUT COOL BRASS 3-4 ROW RADIATORS.
A BIG MECH. FAN AND SHROUD WILL MORE THAN LIKELY HELP TOO --------MILODON HI FLOW WATER PUMP , ------------MAYBE A FRONT AIR DAM---------JMO.
