My big concern which nobody seems to address directly is if you have a big hp engine, don't you usually use a high stall converter? So, if you have a tail OD that puts your engine speed significantly below the stall of the converter, won't that build heat in the trans? Sure, you can add a bigger trans cooler, but it doesn't address the slippage.

For the money, I would go with a modern OD auto with a lock up converter. My opinion is that it would give better benefits.

Depends who you talk to....if it is a GV faithful it is not a problem......you speak wit a trans guy well......

I spoke with Lem at Ultimate Convertor about this very thing when I was thinking about a big cube HEMI with EFI....Len was working with a fellow that had a similar deal. Len told me that the issue they were having was when the t/c was loose enough to launch correctly at the track it was a bit to loose for driving the car on the street and would experience a lot of heat issues as well as some slippage issues....and when it was tight enough to not have the bad manners on the street it was to tight for the track.
This is the very reason why my trans guy, who used to sell GV units a while back steered me away from a GV and into a more modern electronic unit.
As difficult as this is to accept for some folks, there is more than one way to skin a cat. And HIS was is not always the most suitable for all of us.....
