Re: Aftermarket/Replacement Cylinder Head Rule Change
Wow, with all those different Chevy heads it does look like crate engine time. I thought we had it bad with a Chrysler, 2 maybe 3 different ones. Is Ford like that? I know they got a ton of different engines.

Re: Aftermarket/Replacement Cylinder Head Rule Change
So, first;
Do you think Edelbrock did their due diligence and got this head accepted, good for them, or Edelbrock somehow has an "in" and that's why so many of their heads are approved (conspiracy theory?) and this is all about padding the coffers of a company loyal to nhra? Second; I have numerous ford heads in my shop, but they are not the correct year/number/etc so basically they are garbage, even though they are unmolested stock heads. Would love to see the hundreds of ford heads replaced with one as well. Alternatively, I'd like to see all the ford heads that are identical but different years all accepted as the same. Same valve size/chamber size/runners/everything but they have different numbers due to the casting year. Yes some have big/small plugs (no performance advantage) and different rocker arm bolt down methods, but seriously, I'd rather just say if its a stock ford head, then its good. Obviously 4v and 2v Cleveland casting are different and would need different numbers, but all 2v heads and all 4v heads could have the same number. Third; Just questions, don't get your panties in a twist! Lol! Of all manufacturers to get a replacement stock head..chev? REALLY??? Change ford or dodge and you will affect a certain number of racers, but sbc??? AMC, I could see that, or Pontiac...Buick maybe...but CHEV??? How about a caddilac head, I could see that.... |

Re: Aftermarket/Replacement Cylinder Head Rule Change
One of the candidates for a replacement head for Pontiac round port was a head made by Kaufman Racing. Everything was a go but Bruce rejected it because of angled spark plugs. Guess that is not a problem anymore as long as you race a Chevrolet.

Re: Aftermarket/Replacement Cylinder Head Rule Change
This is where I will miss the IHRA Pure Stock.
Basically the Old Stock Eliminator Rules. Seems about that same time in Class Racing. NASCAR Stock Cars had less and less original components! Now not one part in modern day Stock Car ever fit on a Production Car. Same with our car. We need Roll Bars, special suspensions, more safety equipment, certification of helmets and seat belts, special fuel. Cannot even use pump gas anymore. Crate Motors were always a natural fit. Replacement engines were always common. Did not morphed the Stock Eliminator concept. Sometimes you are stuck with a combination. Old parts become problematic! Plus opened up a vendor base. We may not want another class but new ones are always being invented. The RAGE of Racers complaining they do not want a new class. New ones keep popping up. Which means Stock Eliminator has to compete for Racers who choose to run those classes. Current rules restrict inviting the new generation of Racer to play in our sand box. You do not do not see many 20 - 30 year olds. Do see 50’s, 60’s, 70’s and 80’s and passing away. IHRA had the right idea with their Class Eliminator set up. Had NHRA adopted the IHRA structure. There would have been shift from traditional Stock. D |

Re: Aftermarket/Replacement Cylinder Head Rule Change
I'm still perceiving Stock Eliminator through 1980's glasses, because that's what I was most comfortable with. Headers, converter, ring & pinion, and a 9" tire...on a car with a VIN number. Not saying it's better or worse, just saying I'm somewhat stuck in that perceptual paradigm.
But whether I'm comfortable with it or not, Stock has moved on. Just like stock moved on from the '60s, to the '70s, to the '80s, all the way through today. I still find Stock Eliminator fascinating, but it is more and more becoming a class that is difficult to explain to lay people, which I think hampers it's value as a financially viable spectator commodity. Ultimately, I think that Stock is going to die, and when it does, I will very much miss it. It is (and was) a beautiful class. |

Re: Aftermarket/Replacement Cylinder Head Rule Change
How much are angle plugs worth on a SBC SS'er ? Not looking for conjecture.
Real world only, please. |
Re: Aftermarket/Replacement Cylinder Head Rule Change
Bill Jenkins always said 10-12 HP. Chevrolet engineers said it helps more with higher compression ratio and dome in the combustion chamber, but that it was about 10 hp on flat top pistons (350 cu in, 10.5 compression). I have only seen an un-scientific test once on a 377 dirt track engine when a pair of ported 461 heads were replaced with unported 292 heads and the difference was 22 hp.
If high compression benefits more, then consider that all blueprinted 62-70 327 and 350 flattop pistons engines run between 11.5 to 12.0 compression. |

Re: Aftermarket/Replacement Cylinder Head Rule Change
I think for stock the rules should be changed so any casting can be used as long as they have all the same volumes, valve sizes, and valve arrangements. We are there anyway why only allow some manufacturers and people to get replacement parts. Go to a SS cylinder head rule
for stock and be done with it. All the replacement head deal does is give select few racers an economic and performance advantage over the rest. One more thing, all the guys crying that the new cars are not real stockers are wrong. They all have the parts they were designed with and run them. How many original parts are in a 396/375? or a Plymouth 340 with aluminum heads and intake? Not many I’m sure. It’s getting stupid, nobody with a SBC can’t find parts? |

Pontiac doesn't need another approved head. Pontiac guys just need to do their homework. And as of now I read, the Edelbrock Pontiac is approved for Stock. Hesus.......what a bunch of whining no-nothing racers. I fought (voted) against the Super Stock Pontiac E-head every time NHRA asked me. But after 15 years the whiners prevailed. And now Stock? You're shameful. |

Coming from a guy that has never built anything for class racing on his own. Build something on your own, and race against cars that have these parts and let’s see how you do. We will never see that so your statement like yourself is irrelevant.....Next
