Hemi Head Ruling

[jaythorne]

i think david means that the rule never said
"intake side of head may not be cut into any part of valve cover bolt holes
at the valve cover gasket surface"......it just said
"intake side of head may not be cut into any part of valve cover bolt holes"....seems pretty clear to me and has for years...of course it also says that any intake manifold permitted must remain original configuration..ie crossram must remain crossram ...not sure how the intakes of today aare considered crossrams..................

Gentlemen !! whining will not solve that the class is not quit ready for the new rule and the old rule of not going threw the VC bolt hole seams like a clear defined line not to cross

[David Barton]

Can someone please explain to me when this valve cover bolt hole rule existed? Because the rule books I have say nothing about them in the Super Stock section, only in the Stock section. And it states ANY part of the bolt hole in Stock.

If it was applied to Super Stock, wouldn't it be written like the other repeat rules like the head must have the proper casting number, etc?

I'm not sure how many of you understand that Hemi heads have been breaking into the bolt holes since they allowed porting in S/S.

I also want to make it clear that even CW's heads break into the bottom of the valve cover bolt holes. So for the Charlie lovers that think the Super Stock rules are supposed to carry over from Stock, CW's heads wouldn't pass with that rule either.

Well, Brad, Darin & I understand. Refer to pic on page 4. Looks like my $10k is just that, my $10k.........

No disrespect towards anyone, but I'm sorry you and the Reher & Morrison gang didn't realize what the rules were, just like when you got tossed for the boosters in your carbs, or the external mods on your heads. Till this day I want to see you guys perform well. I was excited the day I heard Reher & Morrison was involved in the class. I'm sure if I jumped into Pro Stock there would be more than a few details I would miss that would be obvious to them.

When you jumped in this game you openly admitted you wanted a Westcott engine and a Barton engine for education because you were going to take both of them to Reher & Morrison. I truly respect your honesty, but did you think anyone would send you their best heads with a game plan like that? My Dad respectfully turned down the offer for several reasons. I'm not sure exactly what happened with the other camp. Sounds like the other camp didn't send you the resurfaced heads to copy.

These are the latest two interesting amendments to the rule book as applicable to Super Stock Class:

SECTION 11: SUPER STOCK, ENGINE: 1, CYLINDER HEADS (Page 1) (2/20/2013)

"External modifications prohibited, intake side of head may not be cut into any part of valve cover bolt holes (except for SS/AH). Valve-cover bolt holes must remain unaltered and in their original location (except for SS/AH)".

SECTION 11: SUPER STOCK, ENGINE: 1, ENGINE (Page 1) (2/27/2013)

"Aftermarket crank must retain OEM configuration (i.e., billets, knife edging, narrowed/pendulum cut counterweights, etc. prohibited). Lightening of crankshaft other than normal balance job prohibited. The following are permitted: gun drilled rod and main journals, bull nosed counter weights, any size rod and main journal, additional oil passage holes for rod and main journals."

It sort of reminds me of the old Modified Eliminator rules...

I crew on a comp team, so I have no skin in the game but I do have a observation. After 50 plus years of class racing NHRA is still checking cars the same old way (we will put a valve cover on the engine to see if it fits, really). Time for NHRA to step up and get in the 90's (when CNC machining became popular) and upgrade their technical departments measuring systems. Nascar now uses a 28 point body laser measuring system at the track along with body templates to measure their cars. There are also portable measuring arms that link to a computer to do measurements. Nhra could put a system together to measure all their cars, TF FC Prostock, promod,

Also, NHRA could probably get the dimensions from the manufacturer's of the engine components,(I bet most manufacturer's will give coordinates with factory dimension's on it for measuring)
Probably could get a machine manufacturer to be a official NHRA supplier

Just my 2 cents

When a SS engine costs $60k that should be telling you that way too much is going on there. These cars were awesome when they left with the tires in the air and ran low 9's. I had a lot of respect for them then, but not now.

There are no easy answers, as one way you keep a lot of parked cars out that are a lot closer to the spirit of what the class was meant to be, and the other financially wounds a lot of current cars racing. How many would park their cars with a return to rule enforcement instead of appeasement? How many cars racing now could even go back to the condition required under the rules being enforced? Take a look at some of the chassis in them and ask yourself that question.

If you look at the intake manifold from the front of the car you will notice a slight offset of the carbs which allow the manifold to meet the intent of a crossram. The height of the intake has also been altered and the engines have been lowered on modified k-frames.If you ever go to a show and see a restored Dart or Cuda you can't see the carbs in the scoop. In SS/AH you can them plain as day in the scoop.
