[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?

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.

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.

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.

[72projectbird]

The Hemi is worth more all day long.

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".

[PAUL K]

Anyone know the production number on Hemi's?

Pontiac made around 1200 SD cars total. That doesn't leave a bunch of cars out there to donate their engine parts.
I know Hemi cars bring more money but I always thought that was because Mopars are cheaply constructed and didn't survive the "test of time". Engines were easily saved.

[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.

[sdbob]

I was offered 10k for my running SD455. SR block,73 Intake,nos carb,stk lift cam. A friend owned White Boss 429 Mustang ,4spd,new,I remember car.Had it for a year. I asked him when I see him,do you regret selling it,had to for family,but he says yes ,the guy that bought car,he told me,wrapped it around a pole month after he got it.

[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.

Agreed 1000%

I can appreciate the legendary original 426 Hemi engine. Too bad they were installed in some ugly, cheap ass cars. I equate this to installing the original 12V Cummins diesel in the Ram trucks. It was a Legendary engine in a crap package.

[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.
