I am trying to make a decision on which transmission to swap into my early A body. Ihave a 904 lock up (core) and like the idea of having the bigger clutch pack and other more heavy duty bits and the idea of having an extra "gear" when the converter is locked does have appeal.
My questions ; just what kind of RPM drop do you get when the lockup engages?
With the lower gear ratios of the lockup trans, I would imagine you could get away with running a taller (numerically lower) set of gears, what would be a good starting point?
I was thinking of perhaps 3.23 instead of 3.55 or 3.7. My rear tires are 27.5"
Is there a reputable lockup converter builder that I could get a unit from with a good stall speed? (2400-2600rpm would be my guess with the lower gear ratios in the transmission - the cam is 231/236dur @ .050, .525lift - approx HP 400)
I take my car to local events, but plan on a few road trips in the future - freeway drivability is a concern. (I could just change diffs, not a big deal, but a PITA)
