Re: NHRA allows Alum heads in stock/ss
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. Quote:

Re: NHRA allows Alum heads in stock/ss
At an average of $2500.00 for a pair of old core 690/583 large port 409 heads, which are almost impossible to find within 500 miles... Edelbrocks would be welcome in my world.
Unfortunately, however....in un-molested condition... the Edelbrock heads will not make the power of the old GM castings. Perhaps this is an exception... but this is the fact. |

Re: NHRA allows Alum heads in stock/ss
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.

Re: NHRA allows Alum heads in stock/ss
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?

Re: NHRA allows Alum heads in stock/ss
Jeff,
I agree with you and some others. If you stop and think about it, when I started my way into this, wanting to run the 428FE, if I did not have a motor to begin with finding a good one to start with was nearly impossible. Later when I took my motor to my engine guy he stated that my heads(original) were probably the best since the Edelbrock were cast smaller to leave room to port and therefore showed little if any gains on his dyno. The FE head is so small, physically, that the weight savings is negligible also, and I will not have to carry the extra hp. If I did NOT have a motor, the aluminum head would defiantly be the way to go. Old parts are scarce, worn, and if we want to keep racing, we need a little help. Just my opinion. |

I never said there weren't any small block Ford cores out there, just that it's much cheaper/ easier to get a set of Edelbrocks if I was to run SS
