Re: NHRA allows Alum heads in stock/ss
I`m not sure if all the Edelbrock heads have no exhaust crossover passage or not, but I know many do. Yet with a factory head, you are not allowed to plug the crossover into the bowl area. Also, I`m pretty sure that not all the new heads approved use the same combustion chamber volume or valve sizes for every application that they are approved for. Interesting, eh?

Re: NHRA allows Alum heads in stock/ss
Like the Olds head, the Edelbrock is only specified for SS for the 429 CJ Ford motor (at a 10 HP premium), of which there has been exactly one built in the last 20 years, and it hasn't been run in two years. The stocker still has to run the OEM unobtainium version. And there are those who are bitching about the lack of Chevy heads... don't make me laugh...

Where did this B_ _ L S_ _ T come from????????? First roller rockers and now this! I'm beginning to think the manufacturers are winding up NHRA, the whiners and the cry babies! Just what we need in this economy more unneeded expense. I'm sure Farmer is rolling over in his grave?

Re: NHRA allows Alum heads in stock/ss
How is it an unneeded expense? You don't have to run them, AND in my case in Superstock (if I ran superstock, not stock)it would be Cheaper to buy a set rather than have a set built. I just checked all years of smallblock Ford included (64-81) and can't find a single year or model the Edelbrocks are allowed in Stock, SS only. Others have Stock availability, such as 352, 390, 428, from what I can see.

If the Mopar 452 head is listed in the engine guide for the 1966 383 S/S combo,then it is legal.

Re: NHRA allows Alum heads in stock/ss
Just think of the good part.....When NHRA/IHRA trashes stock you will be all set to run the 10.90 class or maybe 9.90's if you junk is quick enough.
