Randy,
APBA already has a BB spec head, but the real challenge is to make all the different heads make close to the same hp per cu in. I think it would require head/manifold combinations to make things equal.

[randy wilson]

Yes, or simply have 2 different classes in the same class, and index them properly. That would be easier. Also, we could police ourselves with a racers board. Would be way more legit anyway.

oops, I missed your reply SSDiv6. But, on the possible head rule changes allowing a 14° Pro Action head in SS/CS. If the NHRA wants it to become a 1 brand class, that will do it.

[randy wilson]

Well, if true, all GM cars in SS\CS prepare to change heads. For a small update price of, say $13,000 to $18,000 dollars with intakes, heads, valves, pistons, cams, etc. And then get ready for the next step. Allowing aluminum heads in. Then for the small fee of $15,000 you can compete again! Ain't it grand! Should work out REAL GOOD!!!

Makes you want to think about a spec engine with manual trans. Pick the body style and lbs/ci . EVERYONE who drives a stick knows the answer is in the can.

Randy, If you really would like to keep it OLD SCHOOL and keep the word econo in this class, keep the the factory valve angles ( ie sbc 23 degree ). Inline wedge head only.

[randy wilson]

ALL spec heads are factory valve angle. Chevy, 23 degree, Ford, 20 degree, Mopar, 18 degree. Already been handled. You do know we are saying a single disc clutch, min. diameter at 10.5 inch, and NO computers. The right clutch, pressure plate, and fylwheel will be the key. There would be no counter wts. allowed. Clutch would be required to be engaged on ALL shifts. Just saying.

[FINESPLINE]

All right, was not sure about clutchless trans and clutch setup. How about wheelbase limitations and finalizing a lbs/ ci. Starting to think of an old C/SM car !

[randy wilson]

Ain't got that far yet, and actually ain't qualified to make the call on wheel base. Way over my pay grade! Ha!

One must realize that the NHRA and Ford are still doing their dance, for how long the music plays, I don't know.
