If I had it to do again, I'd also look for an already built race car, but I'd also consider a station wagon with a V8 in it (if only you knew Jody Lang)? However, I'm certain that there's plenty of draggin' wagons out there where you are, and since they have the rear overhang, there's money savings on traction improving accessories right there...whatever you pick, I hope you find a combo that hasn't had it's weight break and horsepower factors butchered by other racers combos, and I think you'll have more success in finding a combo like that in the slower 1/2 of Stock Eliminator. I'd also take a look at those Mustangs (like the one Matt Hawk just won San Antonio's Summit Sportsman Spectacular with)...the ones from the 80's- 90's should be cheaper to buy, build, and compete with than todays muscle cars??? My .02
Good Luck in your decision, and welcome to Stock Eliminator!!!!
