Hood Question ????

[Hemiparts]

I see pic of cars in SS running fiberglass hoods,but from my understanding of the rule book you have to use a "factory hood" Does this mean factory appering ( fiberglass that bolts to hinges ) ????? This is the last piece of the puzzle before we start testing for next year.

Good question.

There is a picture of a rambler M/SA with a 290ci engine at the Columbus race with a factory hood scoop that only came on the 390ci version.

If that's legal why can't I run a max wedge scoop from a '64 plymouth 383ci car? Or any '64 plymouth other than the Aluminum scoop cars?

In the real SS/ classes factory hood means just about what it says. If a car came with a nhra accepted fiberglass hood you can run it (and there are some aftermaket hoods that get thru). But you can't replace a steel hood with a fiberglass one unless nhra accepts it. This pertains to the SS/ classes.

Regarding SS classes, if the car came with a steel hood, you must run a steel hood. You can only run a scoop if the car came with a scoop (or shaker, etc.) in the "traditional" Superstock classes). In the GT classes you can run a scoop.
If the car came with a fiberglass part and it is recognized by NHRA, you can keep it that way and it appears you can get away with a carbon-fiber replica. I would confirm with other racers in your class on that.
If your car came with an aluminum part or fiberglass part, you can run a heavier steel version. This is common with aluminum front end mopars for example as the parts are super-pricey and extremely difficult to find. The idea here is you can go heavier, not lighter.

A 290 Rambler in M/SA with a '69 Hurst SC/Rambler (390 4-speed only) would not be legal in NHRA Stock. Maybe it was a IHRA class? I'm not familiar with all of their Stock classes. There probably isn't a better hood scoop out there than that unique snorkel hood scoop. It probably captures as much air as necessary without the aerodynamic problems of something like a '68 Hemi A-body scoop. That's layman opinion not wind-tunnel opinion.

I'm talking about traditional (not modified) SS classes with OEM scoops. If you have a '68 Hemi 'Cuda you get a scoop for SS/AH. If you want to take that same body with scoop and put a 383 in it and run it as a GT car you may. Does that answer your question?

Where would you find this "list" of acceptted hoods. In my case I have a 71 Duster and I know some left the factory with a matte black fibergalss hood. If thats the case I'll just add hood hinges to my fiberglass hood and I'm ready to go.

'71 Dusters came with a steel hood. If you had a 340 Duster it had a pair of fiberglass scoops bolted to the steel hood.
The only post 1970 A-body with a light-weight package is the "Dart-Lite" & "Feather Dusters" as I recall in 1974 with aluminum hoods and other light-weight components. It was a fuel mileage package with slant 6's and overdrive aluminum case manuals trans.

Hey Jeff. My hood scoop is not a hood scoop it's a front mounted parachute. Works similar to lifting at 1000 ft mark

LOL

The lightweight package for both Plymouth and Dodge was 1976 only; the last year for the body style.

Jeff,

If you look at the pictures from the NHRA Columbus race you will see an M/SA 290ci Rambler running the SCrambler hood scoop...how did he get away with that?
