73 GTO HO?
 

just saw one for sale. Is there such a thing as an HO 455 in a 73 GTO? If so,how rare?

No such thing as a true HO in '73. The 455 in 1973 was like all of the others that year. 250 HP.

Production numbers:

519 455 F37 Sport Coupes

25 455 D37 coupe

cleveland craigslist if any wants it

I like that car, but it needs a ton of detail work done to it to make it even remotely worth the asking price.

This car was also posted on the A-Body site . Someone else found it to & the ad says 455 HO , I did send the guy a message to ask what he ment by 455 HO. I don't think he's going to answer me as I did want to know if it my by chance have had an early modle 455 HO engine in it . Maybe he put an HO engine in it , but he has not answered me back yet.. IMO I think he just put that in there thinking someone would think it was better then it is to get a bigger dollar for it.

My father had a 73 455 gto bench seats auto factory gold color. Would this be a rare car?

Just being a real 73 GTO makes it rare, so if you have the car still & it's in good shape keep it & bring it back to life. If you don't have it but can get it back I'd say do it as any 73 GTO is rare & the 455 cars are the few that were made the few of that year. There were more of the 73 GTO with 400's in them. But again to answer your question any 73 GTO is rare as they only made 4807 total GTO's in 73. ANY PIC"S ?????? New or old.

Stolen in 1980, 80k on it. I think we have pics somewhere,I'll look around and see what I can dig up. Bought it from Wilson Pontiac in warminster pa came with moon hubcaps naca hood. He had to get a car eval from Dennis Kirban to get a decent price from the insurance co .

It's a NASA HOOD not a naca hood. :attention:jumping::jumping::jumping:

People who feel the need to correct someone on the NASA/NACA thing all the time should look at the awful grammar and spelling in their posts.

That's funny I thought its a gto hood......

Standard on GTO's Available on G/A's and all other Lemans Body Styles, including the Safari's 73-75

Funny thing is dad had a neighbor with a silver 74 or 75 lemans with a 400 4spd and a ta shaker scoop

Unless it was a transplant, '74 was the last year for a 4 speed (either Saginaw, Muncie or BW ST10) in an A body.

It was a sharp ride. I think it had rally's on it

Those that correct those who are trying to show the correct way of calling things by there proper name are very petty. Now thank that !!!

I've bought many HO 455's over the phone that turned out to be garden variety station wagon 455s

So correcting someone who probably could care less (like me) about the correct spelling of a hood offered 41 years ago isn't petty? I've never taken sides on the NASA/NACA issue because the defenders of each are NEVER going to change the other's minds.

People in glass houses shouldn't throw stones.

Hey makinchips, welcome to the forums! Sorry, we sometimes get carried away but no one can say we aren't passionate about the 73-77 A-bodies.

Rex bought his 73 GTO brand new and has owned it ever since.

I would also love to see any old pics you may have of your Dad's 73.

See what I can do tommorow , got 6" of snow today

Ahem...it's:

Those WHO correct those who are trying to show the correct way of calling things by THEIR proper name are very petty.;)

What exactly dos NASA or NACA hood stand for or mean ?

What years was it optional ? My daughter and I passed on this '75 Lemans last year with a NASA/NACA hood

as a winter beater.

Truer words have never been spoken...

455 , the term NASA is the term for the style of the hood on the 73 GTO. The term NACA is for the style of the Duct on the 73 GTO hood. The NACA Duct was/is a style of the Duct the US NAVY used on some of the fighter jet in the 40's. That style of DUCT has been used on several cars over the years. Pontiac used the hood on the 73-76 GTO/LeMans bodies as an option & as the hood for the 73 GTO. As has been stated before the hood was & always called by the term NASA in all their printed material. Over the years there has been an on going argument about the 2 terms. As some continue to call it by the term for the DUCT & not the hood itself. Pontiac called the hood the NASA hood (like the space agency) in an effort to capitalize on the space race that was going on in the 70's. Pontiac thought it would help in sales of the car . But there are some that insist on calling it but the DUCT term only. Most will know what your talking about when you say either one but the correct term is the NASA hood. There is also 2 styles of the NASA hood . The first style has the vents in the back of the hood which goes across both side of the hood & then the 2nd style of hood is just a flat style hood with the NACA Ducts & no vent stamped in the back of the hood. The 1st style is for the 73-74 cars & the 2nd style is for the 75-76 cars. But there may be some cross over hoods , or replacement hoods installed on the 1st. style cars. The replacement hoods didn't get the vents stamped in the back of the hoods. I hope this helps in your quest to be a real 73-77 Pontiac A-Body guy.

I'm holding out for a 1974 4 speed Grand Am ;)

Would have bought the Lemans pictured above, but I thought $4,000 was a bit much

for the condition it was in.

The NACA hood was not available in 1976...

Too bad this one is kinda rotted, and green on green....

I saw that one too, same color combo as the 4dr one I had but in much worse shape. This one also had a vinyl top.

I'm hoping to get that one I posted a while back. I like the color combo of that one, though. I like these cars better than my '65 GTO, but in reality if you're going to restore one you better grab a few parts cars if you find 'em since the aftermarket offers little.

Guy in high schools mother had a very nice dark maroon 455 4 door with many options; they sold it around '88 or '89 I wish I would have begged my dad for a loan to get it - it went for cheap (around $1,000)

Cool Alvin, I haven't seen that video. I saw Bob Seger at my first concert in 1975. Actually, the headliner was Kiss, but I thought he blew them away (or at least, blew me away). I saw Seger several times over the years after that.

As everyone knows, 'Like A Rock' became the ad slogan for Chevy trucks but the video has a variety of cool cars in it, including a 75 Firebird.

What is a d37 coupe compared to a sport coupe

A D37 GTO Coupe is based off a LeMans 2 door coupe. It has the large triangular glass quarter windows, and a mandatory bench seat. Bucket seats were NOT available in the coupe. The VIN will begin with 2D37.

A F37 GTO Sport Coupe is based off a LeMans Sport Coupe. It could have either the louvered quarter windows, or a rare factory option was the large triangular glass quarter windows. This was available late in the model year. A bench with fold down armrest, or bucket seats were available in this bodystyle. The glovebox door will have a woodgrain applique. The VIN will begin with 2F37.

See the last paragraph. This explains the quarter windows.

What's your email address? I'll send you a couple of pics to post

PM sent

Here are pics of the aforementioned GTO supplied to me by makinchips:

Looks like a pretty low optioned, Valencia Gold Sport Coupe GTO. Thanks for allowing me to share these photos.

He bought it off the lot,ran pretty well for a pure stocker

Per a Hi-Performance CARS Magazine road test in 1973, a 455 GTO ran the quarter mile in 14.7 sec at 91 mph.

http://forums.maxperformanceinc.com/...6&d=1333411507

That's funny I have that issue. It ran 14.90s with 3.08s & 14.60@94. With the 4.10s & the qjet tuned up,4090lbs with 3/4 tank of gas

The 4.10's, while improving the ET over the 3.08's were probably too much for the low CR 455. It would have been interesting if the car had 3.42's like the test car that Cars magazine tested, and was able to get a 14.7 bone stock.

I wonder where they got the 3800lbs figure from. 3.42s might have been better Cars mag only ran 91mph

My low optioned Sport Coupe 4 speed '73 GTO weighs just over 3700. Mine has bucket/no console, no A/C, no additional insulation, bumper guards, base cooling, etc.

That's what I mean the mag car is loaded. Dads weighed 4090lbs
