Going to the track in a couple weeks to test out my new stall/tranny. Before with mods in sig -trans+stall..I went 13.52..What do you think I can run now with a built trans and a 3600 stall / Tune. I am hoping for rock bottom 13s anyway. My main Q is, should I stall as high as I can off the line?..Or just bring it up a little and flash it off the tree? Advice? Only my 3rd time to the track ever.

I've tried it both ways. I think you just have to play with and see what best works for you. My car launches best when I push the RPM's to the point where it tries to push past the brakes.

I think 12.5X - 12.6X is very possible.

5-6 sec. burnout. Try launching from 1K first. Next, try launching from 1800. You should get a pretty good feel for what you should try on pass #3 .

Good luck!

You want to give the converter room to "flash", but where to launch will depend on what your combo likes. As mentioned above, try a few different RPM spots, and if the car hooks really good or spins, try the same rpm again just to verify the results.

I personally launch about 1800-2000 rpm on my 3800 stall in my Nova, and about 950-1000 in the Formula (stock converter). IMHO pushing through the beams won't get you the best results, launching from the beams (giving the converter room to flash) will.

wow, you guys think I could even see a 12.9X?

With a 3000+ stall, sticky tires and a factory 3.23 rear you should hit 12.9's

I know guys w/ just full exhaust, a few bolt on's, 3.73's, 3600 stall and a tune (stock H/C)... cut 1.6X 60's and run 12.1X - 12.2X So, yes ... 12.9 easy.
