Either the car doesn't make the power to go 8's or it does make the power but it weighs too much and destroys the T56. The torque that the boosted LS motors make over the curve, combined with the weight, always kills the trans; even with trans mods like the oil sprayers on the 3/4 gear. I think it can be done, but it will take a sub 3000lb fbody and ALOT of money in the clutch/trans. It'll have a better shot with a slow 60' and a ton of top end.

Good luck to 99bluefbody trying to go 8's while keeping to class weight rules.

Alchemist...In my opinion, no way a 6 speed sequential counts. Faceplated T56 is about the limit, which I believe is what Joe Honeycutt had.

he said he couldnt afford to do what he needed to get it there. so he parted it and made it a nitrous car for a short period then sold it. that is what he told me at the wcf. i know i saw turbo parts and the short block fs on here out of it.

Wasn't Garth Weavers viper making 1500ish when it hit 7's with the t56?

That still doesn't tell me how that Viper did it on a t56 without breaking. How many guys have tried it on a 6060?
