Ram Air Hood
Ram Air Hood
Has anyone bought a ram air hood from Thornton's. If so did it take a while to get it. I have been trying to buy one since past August and finally in Feb they took my order. Still dont have the hood yet but when I called this week they are now saying by end of June.
\FYI - We know what you mean by Ram Air Hood, but that's not the proper decscription. Ram Air was a Pontiac term. The proper way to describe it in Oldsmobility terms is OAI (Outside Air Induction). You will also have to get the air cleaner setup that goes with the carb to make it truly functional as intended by Olds.
Funny you should say that. Same thing I got last year when they were supposed to start offering them for sale in JUNE 2008. I also put in an order; and they never contacted me back. I know they produce a good product. Their price has gone from expensive (1200) to ridiculous 2399 for whatever reason??? I don't know. At one time back in 2005-2006 they were supplying Fusicks exclusively with their hoods. Now it seems that you can't get them from either source. Let us know if you ever get your hood, cause I would like to get one too. But, like you I don't know if they will actually get around to it this year either

Good luck with Thorntons. Hope you get the hood. Shipping will probably cost a lot since they are in PA.
FYI on the louvers you have, one thing most people do wrong with them is paint them all the same color. They are supposed to have 2 colors. the top of the fake lovers, including the inboard line that connects them all up is supposed to be silver. The rest of the louver is supposed to match the car body color - if you need a picure of what I mean, LMK and I'll post it for you. You can get a really good job done at a powder coat shop. I talke to several of them here at a trade show and they said the two step process is no problem, just costs more.
Are you going to put the W-29 graphics on the hood? I'm thinking of doing that with my car and one of the local graphics shops can make this decal for me. It will match GM exactly because the dimensions are in the 72 Cutlass assembly manual.
Post some pics of your car b4 the paint so we can see what the transformation looks like ok?

I dont think I will use the W29 stencil. It looks ok,but not all that fond of it. If I dont get the Thortnton hood then I will paint or powder coat the louvres. But if I get the w25 hood I want to put the w30 appearance on it.The Parts Place sells the stencil or the stick on.

If you put W30 on the car, its not just the W25 OAI hood and air can you install. It means it should have the 455 and TH400, plus FE2 (heavy duty 1' sway bars front and back + posi with 3:23 or 3:42 gears. Also a "misconception" by a lot of would be restorers: 1972 wheel liners were all black; not the red ones that you could find in some pre 72 years. They stopped producing the red liners in late 1970, but you will find some 1971 cars with them. Some odd ball combos are out there with one side red and the other side black. Good old GM - consistent to the end.
W30 emblems are easy to get from most repro stores.
I know what you mean about the stencil. When mine gets put on, if I don't like it, I'll peel it.

Good that you have a 455/400 combo. To check whether it's posi, put both rear wheels with jack stands. turn one side. If both wheels go the same way its a posi. If one turns one way and the other goes opposite - not posi.
To check the axle ratio, put a white chalk mark on the drive shaft. get a friend to turn one wheel 10 full revs. You count the number of turns on the drive shaft. 32=3.23, 34=34.2, 37=3.73 etc. You could also have higher ratios like 2:56, 2:73 etc.
If you wire brush the axle tube on the pass side you should find a set of stamped letters. You might even find the casting number of the axle (about 7 numbers long) Use this link to determine your axle/ratio (assuming the axle has not been changed out). http://www.442.com/oldsfaq/ofocd.htm
Since your car does not have disc brakes, its likely an early model production for 1972. Olds started putting disc brakes in the Cutlass around Mar/Apr 1972. Prior to that they were power drum fronts.

PM me and let me know who you were talking to at Thorntons. I'm gonna call them about a hood for my car.
if you dont want to fake your car up with a w-30 emblem,you could do the triple pin stripe on the side(these are in the wrong spot,should be lower on the belt line),and still do the stripes on the hood,like this car.

Very good looking car. My car was very similiar in color with the vinyl top being the same color as yours,that is a great combo ,same interior color too with the pin stripes also but I am sold on the W30 package and going back with a vinyl as well. I know a lot of people dont like the vinyls but my car had no rust under it at all

That is the first time I have seen a Thornton hood. Looks pretty nice, I would like to see them built. Let us know how the fit is because everything else looks great. How much did that set you back?
I'm wondering if a friend of mine might have been ahead of you in line for the Thornton hood. He ordered, and waited, and waited, and WAITED! Many, many phone calls, and it finally arrived at his shop about 4 weeks ago........BENT!!!!!!!!! He said that their packaging of the hood for shipment left a whole lot to be desired. So, now he's back on their list to get a replacement. Not a happy camper. They build them one at a time?

Are you going to paint the hood stripes on too?I'm also going with vinyl top on mine. It will be black on a silver body with the wider side striping.
I just noticed, there's a pretty good sized gap between the stone shield and the hood tongue. Is there anyway to adjust the stone shield to close it down? I have this same problem on my car; the gap is around 1/2 inch and I've seen lots of them with a much smaller gap.
You are correct they do build them one at a time. They said they have only one mold and it takes about 2 weeks to build one. I intially made an order with them back in Feb and they told me I should have it by the end of March,got a different time table every time I called. I dont see anything wrong with the hood I purchased from them. If anyone wants one of their hood they are going to have to be very patient.
geat looking car and the hood looks really great. I could have gotten an all fiberglass hood for 500-600 but I had seen couple of those hoods here in town and they just didnt fit all that well. Sometimes a lot of work has to go into them just to align properly. Your hoods aligns very well from your picture. I had to think about it long and hard before I bought the hood. My wife thought I was crazy but I told her that you only live once.

PartsPlace hood turned out OK
Well, I buckled and got the PartsPlace hood (steel bottom with glass top). Turned out to be not too bad! Paint is just finished and now it's time to finish putting the car back together !
I see they finally got them, I had called them also. They could not tell me at the time when they were going to get the steel frame hoods for a 72. And I called many,many times. Did it fit for you ok with an modifications? I still dont know how my Thornton hood fits since I am still (slowly) working on my restoration. I thought I would have gotten to the painting stage but I finally finished my floor and now just have to put the brake system on. Did you paint yourself?
Nice

I got a OAI hood from Tamraz and it completely blows. when i got it, the hood looked like it had been sitting in the back of the shop for 10 years. it was all scarfed up. then i tried to fit it, an the hood was warped, the one side matched up ok, then the passenger side dipped down below the fender about 3/4 of a inch. i called them back on it, and they said there was nothing they could do about it. i have had nothing but greif from tamraz, terrible customer service

Sorry for your bad experience.Others have had problems similar to yours when buying these hoods,I know that is the reason I went with the Thornton hood (still no guarantee). Looks like 442 much had much success with his hood, it looks wonderful. I have used Tamraz on many occassions and have never had a problem with them. I bought all of my sheet metal from them with no problems. The guy at Thornton told me that if there is a problem with the hood to send it back before I do any type of alteration on it which I thought was fair. The thing about any part that we might purchase,that is not fitting correctly even if the vendor does accept it back,the buyer still has to spend money on shipping again,so I guess you still loose.

That's pricey! I went with VFN for $595 since the hood is not original anyway.
