Cowl or RA-I hood... can't decide

I painted this car 3 years ago.

I've got two glass hoods, one is a 3" cowl. The other is a Ram Air 1. Can't decide which hood to use, and to go body color or black..




Decisions.. Decisions..

A 3"cowl hood would look mean on that car.

Personally, I think the RA1 hood looks really sharp on thirdgen Firebirds. A lot better than the more popular RAII hoods. The lines of the RA1 hood flow good with the Firebirds whereas the cowl looks better on the Camaros to me.

I vote for the 3" cowl in the body color...

... Or give me the 3" cowl and I'll use it.

Re: Cowl or RA-I hood... can't decide

Thanks guys. Still on the fence. Maybe I should paint both haha.

I wonder if I could somehow get the ram air vents to feed my air filter..

Re: Cowl or RA-I hood... can't decide

Put each hood on the car and take a pic and post them up, then take a pole on which one looks better haha..

I bet either hood will look good on that car.

Ra1 though I think your car could pull either look off.

Re: Cowl or RA-I hood... can't decide

Big fan of the RA1 hood.

There are two styles of these hoods, one has the nostrils further back and angled, the other is more forward and straight. Hard to find pics of them because they are both called the Ram Air 1 hoods.

Re: Cowl or RA-I hood... can't decide

RA1 I think is the best looking aftermarket firebird hood. Not a fan of the RA2's, and I personally don't like the look of a cowl hood on firebirds, and 3 inches is also a bit too big for my taste. Your car, your choice though

Mine is ASCD. The cowl is Harwood.

Ram air:




Cowl:





I've got to spend at least a day on either of them. The Ram air has a few chips. The cowl needs the metal tab-nut riveted back on.

Too bad the IMSA double power bulge hood isn't still around.

I've never actually seen one in person. They looked cool in the photos though.

Is cutting the RA-I hood a nightmare to try and get airflow? One of the reasons I bought the cowl was so I could draw air for the blower since I can't route it to the fender. I didn't realize the ram air hood was blocked off front and rear until I had it.
