Re: How hot do Big Blocks normally run?

Thats too hot IMO. My 402 is bored .30 over and I had the same problem as you. I added two 1600 CFM electric pusher fans on a stock 4 row radiator that kick on at 185 and off at 165, solved my problem. Mine don't get above ~190 even in the summer with the A/C on. No more mechanical fan for me.
