340 demon overheating problem
I have a 71 Demon 360 with 10.5 compression runs on 92 octane I run 11.80 113 mph with a factory rad with 7 blade fan, a/c (8 blade) water pump, with anti cavity shield on water pump with factory pully's and the hightest it gets is 200 on a 75 degree day. It really depends on how the cam is degreed in.
