Breaking in a race engine?

I don't remember your exact combo? Engine wise I believe your 360 has the new Eddy's, flat top pistons, a .484 purple cam, a Performer intake, and a 650ish carb. I thought you may have asked at some point about upgrading from a 7.25 rear? Give us some info on the rear gear and the converter stall speed, along with any other info that may help some of us help? What type of exhaust system (header size) wouldn't hurt either. :D
