Ummmm O/K M/SA - JR COMP -- I like the sound of that.... Now i will quote Clint Eastwood nag nag nag !

Thats a little extreem. A few new parts don't make us Comp cars. Now Modified might be more fitting. At least if you run a car with a Holley carb in stock, then you can run a brand new Quick Fuel 750 with all new parts and no HP penatly.

Before I sold my 69 Super Bee, I could not find a pair of 906 castings out of a hugh pile we have accumulated over the years that were worth the 3k or so it takes, and my old stuff done in l995 were getting weak. I know for one new parts are needed for the old cars and they will run faster. In the case of the Mopars, the old 906 heads were 3/8 stems, 2.08 1.74 valves. The Eddys and Mopar come with 2.14 and 1.81 valves and 11/32 stems. So now one has to put in 16 new seats, 16 new guides, and 16 new 3/8 valves. This I disagree with, and suggested the heads out-of-the-box @ +10 (a bargain for any combo) and about $1500 cheaper. The heads have to meet the specs from the year claimed, hence change the aforementioned stuff, and only get +5, probably still a bargain. A move in the right direction. The original configuratiion voiced by some are gone, like Clark Gable, with the wind. And you don't have to run them, just like the rockers. What am I misssing here?

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

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.

Well then what are you going to do with all your time if that happens. You will not be able tell us we are on the road to hell, and you are the only one who see's it . We will be in hell. I think its going to be a while before that happens.
The aluminum cylinder heads aproved is not the worst idea. Gives the racers who are having a hard time locating 40+ year old castings a chance.
Nobody was up in arms when they allowed a BB Chevy a crate motor intake or brand new D ported exhaust cylinder heads with a GM part # on them. This is just a sign of the times. Alowing new production heads is not an old idea. Now not only Fords and Chevys are not the only people who have them.

WTF!!!!!!!!!!!

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?

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.
