[Half-Inch Stud]

If a fella had a correct 73 or 74 SD455 all rebuilt and verified as fine, dandy, and correct. What is that value?

If a fella had a 1969 426 HEMI, with 4-speed, with all correct accessories, as removed from a filmed running event (1973 crash) & " ran great before removed" is the deal. Belt, alternator headers, hoses bellhousing blah blah to the Trans output yoke, but no carb. What is that value?

I want to know.

Huge difference in price between a 73 four speed Super Duty car and a 74 SD with an automatic... You'd probably get a better answer by asking in the 70-73 tech section.

Are you talking about just the engines, or complete cars?

oh dang, just the engines, in full dress.

I'm a Pontiac fan through and through but a complete period Hemi motor would be worth twice as much. 5 grand vs 10 grand.

[steve25]

Just go on a Mopar site in the used section and your jaw will drop at the price for just the original Carbs off of those motors!

[Formulajones]

Hemi's bring more money no question.

[PAUL K]

Super Duty engine parts I've seen sell/bought in the last couple years

Used shortblock $8500

Heads 3-4k

Intake manifolds around 3k

Distributor $1800

Distributor gear $450

Intake manifolds around 3k

Carburetors around 3k

NOS camshaft $750

Anyone have real world Hemi numbers? Not asking prices but actually "sold/bought" prices.

Many years ago a friend bought a used Hemi 2x4 factory manifold for $50....around the same time I sold an SD intake for $125 ��

Not to say this fellow will get the ask, $10500 for a Hemi block

Many outside the Pontiac community don't know "SD", "Hemi" is an international icon.
Another factor is production numbers, how many SD blocks vs how many Hemi blocks.

Another variable is if the engine in question is the EXACT ("born with") engine for your car. In such a case it could be worth many times what the equivalent service replacement version is worth. At that point, it becomes more about the value of the car as a whole than the "market value" of a generic engine configuration.

[242177P]

Even without the brand comparison, there are still a ton of variables. Rebuilt? That definition varies wildly. Versus an original pulled after four years? That's plenty of time to run a Hemi ragged. And how was it stored for the last 45 years?

I expect the Hemi to command more, because even if you set the Mopars aside, anyone with a hotrod desperately wants one. The SD could find a home in a 63 Tempest, but a second gen bird is much more likely.

Thanks. Interesting, the block I know of that sold for $8500 replaced a block that was purchased for 10k and suffered an unfortunate "issue". The 10.5k might become realistic if a guy suddenly has to have a block now!. That's the best way to get top dollar is wait until a fellow "has to have one now".

Kind of a funny story for you guys about Hemi cars. One of my street racing/hot rod buddies from the 70s and high school and college. Had a show W 30 442 then a 70 383 4 speed Cuda. Sold his 383 Cuda for a Hemi Cuda '71 I believe fairly stock mid 70s last time we had seen each other. We lost touch when I graduated college and moved off. Reconnected about 5 years ago and I asked him "Hey Ken you still got that Hemi Cida you know what they go for now?" He told me" you I kick my self in the ass every day I sold it to buy a Hemi Drag boat back in the early 80s.". He is out of cars and into competitive BBQing. Has a fancy $100K trailer with a stainless steel kitchen and the big smoker that slides to the rear when cooking.

But heck in college you could get a 63-67 Vette for $1500 too-I was too poor to buy one of those even at that price.

[72projectbird]

The Hemi is worth more all day long.

[AG]

I love Pontiacs and that's all I have. If I had to do it over again I would have any Hemi car, preferably a '71 'Cuda.

Along those lines not a Hemi or SD but I had one of the first 35th anniversary 4th Gen LS1 camaros in our area. I was a sheriffs deputy when I had it so I didn’t have to worry about tickets. Anyway time went on and in 2005 I sold it to a guy to buy a truck. The guy I sold it to literally destroyed it a day after getting it. Hit the post for a billboard doing something crazy like 140 MPH. I don’t think he even had it 24 hours

[Firebob]

You just have to realize that Pontiac anything is just not going to bring the kind of dough that a Hemi will. It's all in the advertising. It's the same reason you're going to get 3 times the money for a Camaro as you will for a firebird( basically a better car). It's because of the money spent on advertising. Everybody that owns a Mopar would rather have a Hemi under the hood( even if it was never supposed to be there). You could take a 69 Coronet that originally had a 318 and drop a 426 Hemi n it and the sell price goes from $6k to $120k( well maybe not now but definately a few years ago). I saw it happen. CRAZY.

[Chief of the 60's]

Only a Pontiac purist would pay 2 to 3 times what an SD engine should be worth while any unbiased hardcore car guy knows the value and significance of a 426 Hemi. I dare say that the 426 would outprice the Hemi Pontiac. Take the Hemi out of the equation and I would say the aluminum head 427. If Pontiac were to have an aluminum head SD then by all means the Pontiac would have been king over the BBC.

Now, what would be the most significant engine to date? I would have to say it would be the LS.

[mgarblik]

In actual dollars, it's very hard to say. All it takes is one buyer. There would be many times more potential buyers for a 426 Hemi, so based on that alone, I would think it would bring more $. Chrysler spent decades massaging the "hemi legacy" from the original "FireDome" engine of the 1950's to the Street hemi of the 1960's and the current crop of "sort of Hemi's" They are great engines and very different from anything else Chrysler ever produced. The SD-455, to me is really just a very optimized version of the regular production engine. Strengthened and improved to correct many deficiencies in the regular Pontiac engine and beautifully executed for the time period. Able to meet emission requirements and deliver legendary power for the time. However, the very low production numbers are primarily the driver for the very high prices for parts and complete engines today.
