Torqueflite 904 front clutch question.

I don't offer stock transmission builds and I don't do production transmission work.

But, generally speaking, yes I'd absolutely use 4 thick frictions in the high gear drum over 5 thin, depending on the combination. I will install up to 7 direct frictions, again all depending on the combination. The stock 727 transmissions you build do not need 5 direct frictions, either.
