Thanx. I'm reconsidering the 3.27 first gear in the TKX transmission for the 2.87. I have the standard 2.66 first gear with 3.55 rear gear in a 3200lbs Duster with a small block stroker making 510 ft;lbs and I can be rolling along at 10-20mph, floor it and all hell brakes loose. I guess that big 1st gear is not ideal with street tires.
