4t60e stock converter stall speed
Im looking into getting a converter with 300 to 500 rpm higher stall speed and dont remember what the stock speed is.
And out of what gm do i get the chain drive sprockets to make my stock 2.97 fdr higher for closer gearing.

The Cadillac Allante from 1989-1992 had a 3.21:1 final-drive ratio but their engines had some differences that gave it a 1000 rpm higher max rpm's to take advantage of it. Yes you might gain a little with a shorter ratio but it won't be very much.
About the best you can do for these engines to make them faster are either NOx or forced induction.

I guess ill leave it stock then. I was planning to leave the engine alone, keep it stock and reliable. The primary reason for the trans mods is that i have big heavy wheels on the car, i want something to help it move off the line a little easier for around town driving.
