ok, this is what i have come up with as a good budget build for my car.

Should be a quick little setup, I'm no pro but if it were mine I'd be hoping for low 13 high 12 maybe as good as a mid 12. The converter should be good, I've heard good and bad about TCI but that's they way it goes, look into a Coan Converter I've got one, many of my friends have them with no problems(some used to run TCI) With the suspension, use /6 torsion bars for weight transfer. My Duster is mini tubbed with a relocation kit and I'll soon be doing a pair of 15x10's with a 28x12.5-15 M/t ET street. I've had this tire with a mock up wheel on the car with no problems and the springs set on the lower setting. You should be pleased with your car. Why are you set on a custom grind cam? Why not a catalog cam?
