Factory 3core Radiator BB Nova- Cooling Feedback

[JRSully]

BB Nova's did not come with a clutch fan. The fan (unique to the BB Nova) bolted right through the pulley into the W/P and lets out a very "unique howl" when you wind it up, that is why most of them got chucked back in the day. The fan was needed to move A LOT of air past a big engine in a small area. You can probably get away with the stock set up (3 core), make sure you have the correct shroud and top seal. A 4 core would help if your gonna drive it in high heat. I had my orig re-cored into a 4 and run the original 11:1 L78 in it with orig fan, never gets past 190 on the hottest day in normal driving
