Am I just lucky with my 7.25?

With that being said, I want to get some 3.55s in the back. It's 60 foot time is 2.3X and has no tire spin at all if I heat up the tires. Am I just lucky it hasn't blown? Or is just because it's not delivering all the power at the launch because the stall (no tire spin but it doesn't start going hard till car is moving about 25 mph)? I brought it to the track plenty before I put the stall in as well.

That's because of the gear, putting 3.55's in it will put a smile on your face. I did the same thing when I got my car, I changed the stick and a few other mods and it was still a dog from a start.

I bought a B body rear, completely rebuilt it, installing a suregrip and 3.55's. Wow, what a difference it makes.

With that said, I would seriously look into swapping the entire rear out to at least an 8 1/4. Save your pennies and form a plan, and do it all at once. You won't be disappointed.
