Two questions:

1) Anyone ever used a 3:42 gear behind a 400 pontiac with a turbo 400 tranny?
If so, how do you feel about the gear ratio.

2) What do you think about Motive Gear brand gears??

Thanks

Well, that basicly depends on what your car's motor is built into. 3.42's out to work well, but let me know what set-up your running, and if you plan on going street cruising or straight drags. I have 3.23's in mine, and I'm swaping them for a set of 3.73's I have laying around because mine's not a driver anymore. 3.42's should work well though.

4 Firebirds, mines a 69 Firebird 400 R/A III (soon). Volvo Racer in the works, and just a little bit of everything.

Thanks.........
I'm just building a really stout street driver.
I won't be racing it, but I want it there if I need it!
The 400 is pushing around 500 horses.
Turbo 400 tranny.
I was trying to decide between a 3:73 and a 3:55, when I was on the phone with the gear shop, they recommended a 3:42.
Basically, I've built a 12 bolt rear end and just wondered if I had a big enough gear.
