1.71 in my heavy pig.

 

Several wheels up 1.60's with the SS4000, 3.73's and MT ET Street radials until the rear end spit the spyder gears out. If your staying 10 bolt and going with a high stall with sticky tires to make use of that stall, you might want to have a friend who's a tow truck driver. Seriously, the SS series converters hit the tires HARD on launch with their high STR.
