Guys it can be done for around $60.If you do all the work your self.That is for a car that will run 8.80 to 90s.If your farming the work out then the skys the limit.It's a big jump for 80s to 50s.The cage and motor are what hit you.My old junk ran 9.0s but it was really just a old KOS car.It was 3,500lbs.Had a small tire 10.5 on it too.Lenny
