I've been looking into this as well. The gear spread is better than the Viper transmission, with 5th at .80 and 6th at .63. With my 340 making power from 2200-6400 I would need to run some crazy gears to even come close to being able to use a .50 6th like the Viper T56 has. I mean like 4.56's. Even with a set of 3.91's I'd need to be going over 90mph just to lug the engine in 6th, and I wouldn't see redline until I was doing about 250mph. :-k
Plus the American powertrain units come with the provisions to use a mechanical speedo, which is great because I want to keep my rallye gauges.
So, that one should work with the Quicktime RM 6076 bell for a 340? Any other thoughts/recommendations?
