I have a 63 Polara with a 383 and 4 spd. It has a 280 degree Isky cam, offy intake, AVS carb, and Hedman headers. It has a 3 row 16 fins per inch rad, 7 inch pulley, and a 18 inch good 6 blade SS flex fan. This combo works on a 90 degree Oregon day. You must be very sure that all coolant passages in your block are clear of crud. ----- Original Message ----- From: "Schuyler Wrobel" <sky62@xxxxxxxxxxxxx>

I'm using one of those viscous fans now, what are, from what I understand, designed to free up horsepower by allowing a little slippage, mostly at higher RPM.

Just curious. Are you all measuring the outside diameter, or using the bottom of the groove?I also don't understand all the overheating problems. I've run scads of mopes with big blocks, some stock some far from it. Some with air. B bodies and fat old C bodies. The only overheating problem I had was on a '70 Superbird with a 440 6bbl, but they were notorious for heating with the tiny air opening under the nose. Even the Daytonas had better openings. Even so, it was only on very hot days, and didn't so much overheat, as just run hotter than I was happy with.My '63 (383) used to run just a bit hot in traffic, untill I remembered slapping a little 4 blade fan off an old poly on it when the bigger one showed a crack. Changed that and problem solved.All good info though, should the need arise.
