No matter how you look at it, the 65-66 17" hole is way to small for a high performance small block..
Not if it's a 6 banger.
Larger rad = better cooling.

oldjudge said:The reason for changing thermostats is to get better heat in winter. I am using a stock 4 blade fan, does anybody have any suggestions on a better one they've had better luck with.
dodgestang said:I have to disagree with you on that one. I too used to think that I had to cut open my radiator support to get a large enough radiator for proper cooling, but I proved myself wrong.
I added a griffen bolt-in HD aluminum radaitor and a spal 16 elec puller fan into my 65 to cool my VERY high performance 408 Cleveland stroker. The temp gauges never even gets to halfway so matter how long I sit in one place (ie traffic) and idle.
I also got this puppy special ordered with a slight modification to the mounting flange that sucked it further into the rad support moving it slightly farther away from the front of the motor so that I had more clearance in front of the water pump:

mdjay said:Maybe in Maryland! Although the aluminum issue has already been mentioned, come out here where it gets 115 degrees all summer, 100 degrees at night and we'll talk! We play with this issue every summer... "Temp gauge half way?" Is that a h/c gauge?
dodgestang said:lol - of course its the idiot temp gauge....I spent all my money on the motor so I haven't been able to afford that JME gauge set I plan on putting in yet
However, sitting still on a warm day doing a cam burn in at 1500-3200 rpm for 45 minutes with the electric fan wire to just always run the temp needle barely broke into the standard operating range, so I feel confident enough to drive it out to Vegas and show you this summer ..... if it overheats....I'll be proved wrong and pissed off
Based on your input, an optimum solution to overheating can only be achieved by first addressing location, so if he lives in the Southwest I will seed that climate may be an issue, however, do we know where he lives?
I do have the benefit of not running any accesories other than an ALt....no air, no power....so I gain a benefit there
