Idk about Indiana, but they tried 602 Non wing sprints here in FL at 4 17 Southern Speedway and it never took off. I think they ran 2 or 3 races, drew like 5 cars. More series with different rules= lower car counts everywhere

I've seen Race Saver 305 run top seven in boss at Atomic and Attica/Fremont 305s run top five at eldora. Think it's a heck of a starter setup. Think all that other stuff is just that.. something that gets started and not well supported or able to draw from outside its group.

But that Baldwin 925 horse two and a half seasons between refresh might be a option for some to get into the sport and stay awhile in full up Non Wing Sprints.
Info on it

Engine information from Baldwin Racing Engines:

We have finally got together a full quote for a turnkey LS410 Sprint engine. Dart aluminum block, billet Callie’s crankshaft, Dyers rods, custom CP pistons w/DLC pins, custom All-Pro heads w/Ti valves, DLC lifters, Jesel shaft rockers, custom Billet Engler injection, Wolff 5 stage pump and plumbing, Olson oil pan, water pump and all plumbing. Engine weight was 340#, engine chassis dyno’s at Engler 880hp and 685lbsft. So the engine roughly makes 925hp and 725lbsft, much lower cost of operation. Great drivability and power. Complete package is $45,500.00 so considerably less upfront cost as well. Contact us for more info, 3 years on run time on this combo with great results.
