Looking like the 4l80 is way out of the budget right now. I have been getting lots of trade offers for T56's, so that is what I might do.
My car has WAY more power then it needs to do 200 mph. In the standing mile, I may only get to 195 or something on pumpgas, but thats fine with me on 93 octane. That will make me happy.
If this brick (picture below)will do 188 with the supercharger belt flipped over 9 seconds from the finish, I feel confident I can do close to 200 also in the standing mile. I could always put race gas in and run way over 200 mph in the standing mile, But I would be happy just to try a 93 octane run at it!
