In our big block stockers it would be impossible to be competitive

without a Pro trans 727 with 904 internals. My kids Roadrunner picked

up well over a .10 over our aluminum equipped low gear 727 by Pro trans.

That is the difference between first round loser and Class Winner a couple weeks

ago at Sport Nationals. Both hold up real well as long as you change trans oil

regularly. Until NHRA allows an adapter for big blocks to be legal you

need a 727 with 904 guts to be competitive.
