would sponsors pay for a new engine and tranny, or how bout a rear wheel drive conversion, will they pay for labor or just parts, just trying to figure out whats possible thanks for the help

If you haven't got any sponsors yet, then it'll be hard for you to find a sponsor that will do all of that for you... I just started with the whole show/race deal, and I have to tell you that you have to start small and work your way up. I currently have two sponsorships, and am in the process of building my car, so when I get done (as done as it will get for a while lol) I'll have a better chance of getting better sponsorships. If you want to get started, go to www.carsponsorships.com and see what they have to offer you... they usually start you off pretty decent, with something small to build off of.
