Thinking about putting the Viper 5th and 6th gears in my stock t56. Is it worth it? What all is needed for the swap? What differences did you notice afterwards?
main reason I think it would be more worth it to me is because of the 4.10’s I have, think it would actually be worth it with those?Friend of mine did this mod to his 04 when he installed 3.73's. He actually wasn't a fan. He said any time his was in 6th any acceleration put him into boost. And with a 3.4 Whipple it wasn't a small amount of boost.
You have to remember these are small engines. They don't like lumbering along at 1500rpm. They don't have the torque for it. I usually cruise at 80 too, but I wouldn't want to have to get there just to use 6th personally.
I think knowing the kind of MPG @Roush6018 is getting compared to what you get is worth knowing. And knowing the type of area you drive in. Flat areas are different than hilly areas.
