If the results don't match the theory, change the theory.

always used type f whats best ?727 street strip 9.0 converter full man valve body bb engine I run Type F, but use Redline's synthetic version. I believe ATI's synthetic ATF is also Type F, FWIW. Street use with the additional heat & slippage from a high stall converter rules out standard (non-synthetic) ATF for me. I also use an accessory trans cooler. But that's my approach and others may not agree.

BradH...I don't doubt the synthetic is better w/ heat. Just throwing it out there that the normal stuff works fine.

Synthetic is a "peace of mind" thing for me. Years ago I recall seeing some tests showing at what temperature conventional ATF started to break down vs synthetic, and that persuaded me that I'd be better off w/ synthetic. If I can’t hurt Dextron 3 or type F I think you are fine. A powerglide and transbrake really test how good your fluid is. Zero issues

If I can’t hurt Dextron 3 or type F I think you are fine. A powerglide and transbrake really test how good your fluid is. Zero issues Is that before or after you drove 100+ miles one way to the track every weekend for a month? All I'm pointing out is that I don't think we're all looking at it from the same perspective. The OP said a street/strip car w/ a high-stall converter, which fits with my experiences. As I said above, not everyone is going to take the same approach that I do (and that applies to a LOT of things ), so I don't know why people feel the need to reply in a manner that insinuates that I'm "wrong" and they're "right". People -- obviously -- should run whatever they want. I'm glad others have good results doing different things than I do, since I know how much it can cost to make bad choices that hurt reliability & performance. However, the guy asked for an opinion and I provided mine because his application sounds very similar to mine.

One of the aircraft mags I use to get had a article about synthetic oils that said standard petroleum based oil molicules would start to break down at 325F and that the synthetic based oil molicules, back then, mid 1990s, would start to break down around 525+ F I do remember reading about the dye in all automatic trans fluids back in the early to mid 1960 that stated that the dye would start to change colors at 275F and go from red to brown and become black at or above 325f
