3.55 vs 3.91

I'd run a 3:73 or 4:10 with an adjustable snubber for street/strip use, your choice.
Best guess is you have about 400hp, an 8"wide tire will hold if you've got the suspension dialed in.
Tire size would be what ever hooks best on the track and you can get under there.
I'd lose that stock convertor immediately and go with a 2200 to 2600 stall for
a decent all around street/strip package that can be driven daily without a bunch of headaches.
A trans cooler is a must.

That is about right for the power of my setup, the suspension is a work in progress so I will get dialed soon. And I am wanting to get a new converter, I know that is another thing that is probably holding me back significantly. I am slowly building this car up so Ill get a new one over the winter as well as the rear end.

I went from a 7 1/4 2.76's to an 8 3/4 3.55 suregrip.

Let's just say the look on your face will be priceless, the first time you mash on it.

Well I'm glad to here that! I am looking forward to putting in new gears the more I drive the thing. Wish I could see my own face when I do, I know I'll have the biggest grin on my face! LOL

I have found a set of 3.55s fairly close to me, and a set of 3.91s, I am going to try for the 3.91s but if not, I will have a set of 3.55s to run around in.
