In 1989 I built a PAW blower motor kit: chevy 350 with a B&M supercharger and a B&M superjection kit.[about 400 hp] This was installed in my Datsun 240 Z with a Nordskog kit. The tranny is a GM 350 turbo. Initially there were cooling problems which were eventually solved with a 3 core radiator, oil cooler, and accessory trans cooler. This combinationj has run well for nearly 20 yrs, but now it gains heat at highway speeds. I think I need to redo the cooling system. The question is, what to select. Motorsport lists several radiators: 3 core, 4 core, 4 core crossflow, and 4core cross flow aluminum. Should I keep the add on oil and trans coolers? Any advise will be welcome, Bill
