First off stick with the motor in the stock location. For all the work involved with pushing it back in the chassis for better traction, it's more work than is necessary. I don't know where you're located, but ask around the track and see who builds a good transmission and go with them. Having to ship a trans. back and forth to another state takes a lot of the fun, and track time, away from racing. But you might want to consider Abruzzi or Rossler transmissions. Call them and they'll give you the best combo to use. If you're going to bracket race consider a Glide. I know a Glide is a boring ride, but you're looking for consistancy. Your best bet is to back half the chassis with something from a well known manufacturer (S&W Chassis) and put a narrowed 9'' Ford under it with ladder bars. If you step up in hp you can go with a 4 link later. And don't forget all your safety equipment too like a cage tied into the chassis that will help stiffen the chassis.
