Stan,
glad you talked w/Yank.
2400 - 2600 stall will really wake up that 292 out of the hole.
But, like you said it is more for back road usage & not really made to race so I think a stall of 2400 tops is all you really need, but the choice is up to you.
Good luck.
Did you talk w/anyone else about converters?
