I agree.

We have limited the air intake to 750 cfm, and the exhaust to 2" primaries.

Why don't you use the old C/Super Mod rules from the 70's when it was introduced.
no porting, any lower end. at the time over the counter manifold. 750 carb. no big tires, etc., etc..

Bob, I actually have applied some of the rules from the old C\SM, and SS\CS. I never ran C\SM, but ran SS\CS for years, and ran D\EM, and C\EM IHRA. We weren't going to allow any porting on the Brodix spec head, and about the only difference is the tire size. The classes are close to the same, and might be interesting. The head potential is almost identical. As of now it's just an idea, nothing more.

The old C/SM head rules were cheaper than a set of Brodix heads. Had to be production iron heads. Stock valve stem size, only 1" below the valve seats, 1/2" back from the intake gasket surface to match the manifold. No welding or epoxy. We had more C/SM cars in class at Indy than in SS eliminator at many races today. Guys that liked to write big checks were no faster than guys with a clue what they were doing. You can hide more work in aluminium heads than iron. With the 1970s C/SM head rules there was no reason to send anything to Brodix, or anybody else, for verication.

I am assuming this thread is just off season fantasy stuff but OK, I'll bite. You realize that any one of several Comp racers would make a mockery of this in no time. This will instantly turn into a $100,000 car class dominated by a handful of racers. How much fun do you plan to have when you get your butt kicked in the first round every week? Stock has very restrictive rules, look how cheap they are to build. So how do you intend to enforce a 'must clutch' on the shifts rule? Is a tech official going to ride along or do you have to download your GoPro after every run? Sorry to ruin your fun, please procede with your fantasy of believing there is a way to devolve racing back to the 70's.
