Its expensive but put a race pak in it. It will tell you what you need to know. I moved from super gas to comp elim this year. Same car. 34 chev roadster. then, 350 490 horse SBC on the stop for 2.50 9.90's at 142 to 144mph. Now so far 9,70's at 134 with a four cyl. Same weight. Car wont get out of its own way in the sixty foot. spin bog spin bog, once i get that figured out i will be faster. Without the stop on when you leave you are probably spinning the tires on the launch, even though your 60' maybe faster by a bit you are loosing your et and mph at the hit of the throttle. We are movving from a 31.5/13.5/15 to a 30/10.5/15 and should be faster. big tires are not always better.
