Like Jet said if you are just looking to get seat time its fine, but if you want to be competitive you will have to go with a 604. Chris Steele, Brad Hall and Mike Phegar (sp) all ran 602's last year and all went to 604's. The Hoosiers have a lot more bite and they do not spin like the Good Years. This made the 604's faster and hurt the 602's because when the track got slick the 604's would be spinning and the 602's did not spin as much due to lack of horsepower. Fastrack givs you a 150 lbs weight break for running the 602 but your motor is around 50 lbs heavier. You have to weight 2250. Getting down to this weight is hard to do and keep your %'s is almost impossible. You can get this low by buying all of the low weight stuff but by the time you buy all of this you could have bought a 604. Carbs do make some difference but Chris told me the biggest difference between any carb he dynoed was around seven horsepower. I run typically 6th to 12th out of a 24 car field. The biggest problem is quailifing. When the track is wet the 604's are hard to keep up with. If money is not an issue I would go ahead and get the 604 if it is get the 602. I race for fun because the most money my car makes is when it is in the Gararge.lol. Good luck with which ever you choose.
