OLD Modified Corvettes

[Mike Taylor 3601]

I like your ideals,the spec head,I believe is the equalizer between brands,and best for cost.
I think two things that would be required though are high side rev limiter,and wheelie bars,I like the ideal of 14X32 tire rule like SS has that Dick added,does'nt mean you have to use 14X32 but that is biggest you can use.
High side limiter is money saver,when you are spinning stick car wide open on starting line and break on launch,rev limiter will save bottom end,and will get you out w/bent valves at the worst.
I believe running mod type car w/out wheelie bars is risky and I don't know of any good reason not to have them.

Pictures of Granny Goose car brings back memories,My Dad has told story as long as can remember,about one of his favorite wins,was big race @ Mt. Park he beat the Granny Goose car in 1/4 finals and had bye to finals and was gave option to set it out so he was sitting in lanes wating for final round,Dave Lewis came over pulled money out of pocket and said this car ain't legal,my Dad said I tell you what pull yours over hear and you pull a bolt and I'll pull a bolt,he said Dave put his money back in his pocket and walked off.

Mike, I like the idea of any size tire. I like the idea of a rev limiter, I like the idea of wheelie bars. I was just incorporating others thoughts, along with some of mine. I own belt drives, star vac pumps, external oil pumps, etc. Just was trying to appeal to those who fell by the wayside, because a $1,000 here, and a $1,000 there, and pretty soon, you're talking about some serious change. I think tires are a non issue now. Same with wheelie bars, and rev chips. The heads are, and will be the limiting factor. As long as they never let a gray area in, and stick to the rules.

Do any of you guys think it would be worth the time to send Scott Gardner a set of our thoughts?

Refer to my previous post. I've even read this thread and still have no idea what the rules would be, who would build these cars, how many cars there would be, if it would be a participant-based class, a spectator-based class, what would draw sponsors to the class, ad infinitum...

If you send an e-mail saying, "Hey, we want to run old cars kinda like Modified only totally different, like a cheap version of Super Stock", nobody's going to know what you're talking about, and it would be likely to get little response more than, "OK, that's nice."

You need a BUSINESS PLAN. Until you can put together a coherent, solid program here, you're not ready to approach sanctioning bodies, tracks, promoters, or sponsors. That plan or program may go through some adjustments over time, but you need a solid starting point.

I don't say any of this to be a downer: on the contrary, I hope it motivates and focuses your efforts. Get a baseline, and write it up in an outline or rulebook format, and post it here. Refine, and then tackle the business plan end of things. Just like with any business, marketing, or sponsor deal, the person on the receiving end is primarily going to be interested in how it benefits THEM. That explanation is going to have to be more precise than "Because it's wicked cool." Ask yourself all the questions that anyone in those positions would ask you, and try to answer them.


...if you want to equalize the playing field and reduce the ability to make gains by spending money, limit both the intake and exhaust -- and I'm not talking about the cylinder heads or camshafts... think air.

In response to Michael Beard's post. I agree. These are not rules, just an idea. If I print the rules, it will be influenced by MY thinking. I'm just trying to feel it out, and see what MOST want. When I wrote em for my track, it was simple. I had to try and include 40, or 50 local boys. This is a little different. Our old heads up website has since been cancelled, or you could observe that we were pretty explicit. I know you're trying to be helpful, but I honestly don't know the proper way to approach this, other then maybe getting Brodix to do it on their own, and that's a stretch. I truly could write up a rule, that looks professional. Then is that the rules? I doubt either NHRA, or IHRA give a damn what I think, so no, I don't actually know what I'm doing.

[Michael Beard]

As I said, you just need a baseline. Again, I've read this thread and have absolutely no idea where the class is right now except a spec head. Right now you have ideas scattered through 10 pages of this post. Consolidate everything into one post, written up in an easy-to-read outline that everyone can follow. Discuss, tweak and amend. It doesn't have to be 100% final absolute -- there will always going to be adjustments made down the road.

The Class Nationals planning thread went the same way. The idea we started out with isn't where we ended up, but we put forth a fairly solid plan and revised as we went until arriving at the final product. Even at this point, we know that there will be changes made in 2015, but we need to get the first year under our belt to have real data and make informed decisions on scheduling, classes, etc.

I agree.

[randy wilson]

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

[Bob Lasko]

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..
