Inching into 12's..... 2.94's vs 3.23's

Ok, been a lot of questions on "what's next ?" both here and my Utube channel. My next most probable step will be addressing the transmission. I feel fortunate that a stock 904 would take a pounding for 5 years and still be going strong. Amazing, actually. I have purchased a 904 that's been built for drag racing from a guy that builds transmissions and had this one set up for a back up for his race vehicles. It's never been run since being built. He sold it to me for nickels on the dollar. I'm just weighing options on the converter.
