OLD Modified Corvettes

[randy wilson]

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.

Ed they can hide the grinding acid in stk why wouldnd they do it in this class?

[Ed Wright]

They could simply put a port CC limit on them, like in SS now. Some of the Stocker heads I have seen make me think somebody is not looking real hard, or aren't that familiar with some of these castings. If you know cylinder heads well enough to know where to look.... Wesley knows cylinder heads well enough, I'm not so sure a lot of these would get past him.

I believe I know where this is going, and I could spot an illegal spec head without a whole lot of trouble. Then if there was a discrepancy, Brodix could make the call. They have several years experience dealing with every conceivable mod that has tried to slip by in the 360 sprints. The benefit is you are policing one head. Not 47 classes with 67 different head combos. Big difference.

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.

Good job on establishing a baseline set of rules. That was something even I could understand.

Want to address Caughlin's infinite money Comp-racer issue? Refer to prior post: Restrict the air intake and exhaust. What you've done is a start, but consider what you could do that would be easily policed that would substantially mitigate the effects of people spending massive money on anything... whether it be highly modified carburetors, doctored cylinder heads, etc.

There's actually an interesting solution devised by a mad scientist racer many years ago. I did extensive computer modeling on it, and it works ridiculously well, despite (or perhaps because) it being very simple.

[randy wilson]

Michael. I'll bite. Anything that works. Jim. I doubt very much even a comp racer could fool the manufacturer with all the computer controlled design today. Get real. Super mod evolved to where it is today because of innovative racers that at that time, were tough to catch. Today, not so much. I know a guy at Brodix that said "Bring em on, we'll decide who's smarter." On the clutching every gear thingy. Let me respond. At our track, if anyone was suspected of shifting without a clutch, a protest fee was paid, then the car under protest was required to make up to 3 runs, backing up his other runs that night within .02 in the 1\8th, and .01 in the first 60' with, now hear me out, a roll cage mounted camera recording the left foot. What do you know, it worked. I still have the camera. I was going to get more detailed later. I was just throwing options out there. I think going back to actually driving a race car would be far more interesting. By the way, no one has to send their head to Brodix unless they are under protest. Surely the comp guys, ( who I have the utmost respect for) don't need to cheat to beat a bunch of redneck hillbillies. I welcome the challenge, thank you.
