Another question today.

So I am putting a 700-R4 in the car and was looking at torque converters. A couple friends recommended a 2250-2400 stall converter. Then someone mentioned that if I get a converter that has a higher stall (2400) than what my final drive RPM is (hopefully 2000 or less at 70mph), I will burn up the transmission. It seems I have read about a lot of guys who have a 2400 converter and use a 700 and get the lower rpm advantage.

any thoughts here? Any other information needed to make educated comments?

just in case, it is a 406, 700R4, 3.73 gears, 245/45/17. looking for about 2000 RPM in Overdrive at 70mph cruise.

NOT TRUE!!
First off......Your converter only "Slips" when it's under MAX load.....NOT so much when cruising.

Secondly, the 700r4 uses a "LOCK-UP" clutch in the converter that locks up when at light throttle in 3rd and in O.D. :yes:

I had a 4800 stall in my wife's car (with a 700r4) and NEVER had a heat related problem. Once the converter locked up, it was no longer a "Stall".:no::devil:
