a lot of that comes down to personal preference......I have gone through just about every option on my car, built GS tranny, built TH400, built TH400 with gear vendor OD, and now the V160. The V160 is by far the best set up I have had in my opinion. The TH400 was great for drag racing, but the 6 speed is awesome for the street fun factor. I would never go back to anything else if I was given the option for free. Just my .2 cents.
