Access to AMA Shipping Weights?

[Larry Hill]

Like I said a lot of interesting information in the AMA sheets: a 68 FE 390 valves are ground on 45* for all Hp listed. The 427FE valves are listed as being ground on 30 *. Both the engines with 4V listed as .4809 lift intake, .490 exhaust, with hyd lifters.

Ford had a daisy chain on the engine adds, from a 302 2V up to 427 4V. This is the chain on a 1968 GT Torino Fastback your choice of starting weight.
Curb weight. 3362# About 95% of curb weight Shipping weight 3208#.

390 2V vs 302 2V +243#
390 4V vs 390 2V. + 37#
427 4V vs 390 4V. + 70#

A similar process is used on the transmissions

Over night, Larry's and many other six packs went from a A/SA to a natural C/SA. Can now run D/SA. What the....? Obviously B/SA will have a new fast car.

I meant to put C. It was a "B".....lol late night typing.

Mr Joe now it figures 9.18 lbs per rated HP =C

What I cant find in the AMA sheets and I've looked at 1967-1972 at all of the Ford stuff. I have yet to find a .527/.527 lift camshaft for the 428/360/335 engine. You would think it would be highlighted in yellow.

Possibly need a lemon and a hair dryer to see it.

I guess Dwight`s site has not updated this new development, but upon looking at the 70 Barracuda/Cuda page, couldn`t help but find it interesting, that unlike most other combos, both the 340 and 440 6 barrel combos are rated considerably LOWER with Edelbrock aluminum heads, than the factory iron heads. the AAR 340 3x2 is rated at 319HP with iron heads, and only 304 with the Edelbrocks, and the automatic 440 6bbl is 395 HP with iron, and 377(!) with Edelbrocks! Pretty sweet deal, the Edelbrock heads allow the car to weigh 150 pounds less than iron. Any other combos get less HP with aftermarket heads? They must be a real awful "upgrade".

Ya know, I was under the impression that when this whole thing went down you had the option of using the "easier to find" aftermarket heads BUT with a 10 HP penalty!
Some how, the Mopar aftermarket heads were allowed to become a separate combo and are now judged by themselves. Probably had something to do with a prior NTD.

Hey, maybe the new guy in charge should have a look at straightening this mess out.

The heads came with a penalty of Hp. The current Hp is correct

In my case (1980 Aspen RT) it’s unlikely any weight change will impact my preferred class. So I complete the online tech card and it pre-populates the card for the next event, so now I have to verify before every event that my shipping weight and P/W numbers haven’t been mysteriously updated by NHRA which would technically mean I could submit an incorrect card? Completely expect that NHRA Comp page should be updated anytime a platform is changed. Hello, Lonnie?

When you go to a store to buy milk and price is marked $2.50, at check out the milk rings up at $3.75. The purchase is made and latter consumed but the sour taste of the milk lasts forever. The best surprise is no surprise.

No, they're NOT correct!
We were SOLD the aftermarket head premise based on the fact that you could use the aftermarket head with a 10 HP weight penalty based on the factor of the correct iron head. This is now being treated as if the aluminum head is an entirely different combo, which it's not.
It was never SOLD to us as being a different combo. It HAS been re-constituted and FED to us in this way.

Here I go "hi-jacking" another one of your threads, sorry Buddy.
