Re: How hot do Big Blocks normally run?

My 2wd Blazer has a mild 454 +.40, 236 peanut port heads, Performer RPM, headers... and runs COOL. Idling a long time on a hot Florida day it won't go over 190deg. At road speed it drops back down to 160. Factory gauge with the sender in the intake. It has a 4 core GM radiator, factory shroud, 7 blade clutch fan, aluminum water pump and an A/C condenser in front of the radiator(don't use the A/C 'cause I never put the top on). I haven't had a timing light on it in years but it seems to run best advanced 'til it bucks against the starter and backed off a little.
