I appreciate the response, though I think some misunderstood the nature of my query. I'm not looking to prove or disprove the validity of carburetors over injection or vice-versa. My goal is to try and get a non-wing sprint class going in my area, where there are NO SPRINTS. To say I face an uphill battle is an understatement, but that's my goal. I still love dirt late models but recent changes in the rules and the general trend in the class, even the crates has put DLM's completely out of reach, both monetarily wise, tech wise and time and help needed to run competitively. The new rules they put in place I think only further separate the elites from the blue collar more. Having said all that, in my down time last year I discovered a new class called the NorthEast Wingless Sprints, using a GM602 w/HEI and a carb as well as a small transmission and a starter. Now I know pretty much everything about this package makes the diehard sprint guys cringe and feel nauscious, I understand. What you have to understand is, where I am, everything sprint people hold near and dear, is as foreign to us as if it was martian technology.
Now those 602 sprints I think might be inexpensive enough and simple enough to actually get guys to take a chance on racing non-wing sprints. Tracks around me are NOT setup with push vehicles, or push off areas or any of the infrastructure required to pull off a regular sprint show/class. So, the transmission may be a sacrilege in Indiana, but here in Georgia it may just be what swings people over to give sprints a chance. Once they see how much easier they are to work on and how great the racing is I think it'll take off.
In my research I've found 3 likely ways to go powerplant wise, GM602 w/carb, GM604 w/carb, CT525 w/carb and Racesaver 305 w/injection. I don't like the 602, especially since its treated as "disposable" and its anemic, but the price makes people willing to give it a go. After watching an untold number of youtube videos I think the racesaver 305 is the raciest of the group, but the injection and the price of it and the CT525 may be a bridge to far. Another thing to consider is, 305 racesavers Wing cars already exist in the Carolinas and a few I've talked to expressed interest taking their wings off and helping get the class going or at least putting on an exhibition or two. Anyway I've wandered off.
Ok the GM602 is rated at 350HP on gas w/carb, when its switched to alcohol carb it goes to 400HP, would putting injection on it make it anymore powerful or racier? I only ask because I once saw a dyno comparison of an engine switched from carb to injection and the injection made the power curve much flatter, where the carb kinda swung down before regaining on the top end, w/peak power nearly identical. I only mention this as maybe adding injection might make the GM602 race a little better.
