375 hp on single 4 392s. A 440 is generally cheaper, same power, direct bolt in, same or more hp stock, wieghs less, and you wont get the 'Yea but its not a 426 hemi" comments every time you pop the hood to show it off.

and 392's are heavy. Parts are very expensive, especially speed parts.

“…..Ya but it's a Hemi……..and can't afford a 426…..”

That is exactly what I think when I see a first Gen HEMI in any MOPAR built after 1963....someone who took the cheap way out.

There is enough difference between the 1st and 2nd Gen HEMIs that anyone who knows MOPARS can tell at a glance it’s not a 2nd Gen. Don’t get me wrong I like the 1st Gen HEMIs, I just don’t think they look right in anything made after the introduction of the 2nd Gen. I also think you would find that in the long run it would actually detract from the cars resale value.

As far as the value of the engine, a lot of people ask a ton of money on the 392s, but the ones that actually change hands usually go for $1000-1500 in complete, builder condition. As far as having the transmission..... that would be the heavy cast iron torqueflight with the big emergency brake on the back. It’s really only desirable to restorers. To put a modern torqueflight behind an early HEMI you will need a Small Block 727/904/518 and an adaptor plate that runs in the $500 neighborhood.

If you do decide to look at the engine make sure you look at and print out the engine ID Codes from the Hot Hemi Heads site. There were something like 13 different displacement 1st Gen HEMIs produced between Chrysler, Dodge and DeSoto. Almost every early HEMI I’ve seen advertised claimed to be a 392....over half were not.

I 100%



Not only that, youll likey spend more in total than just buying and installing a crate 426 with a 392 requiring custom headers, engine mounts, trans adapter, rebuild costs, etc. etc. etc.

OK..my turn. Anything over a stock rebuild is where the costs are. For a basic build, I would say prices are 15-20% over a 440. Cast pistons are available. King makes the bearings. New and reground cams are there. Melling recently reintroduced the oil pump. Fel-Pro still manufactures the gaskets, along with BEST Gasket. Getting it into the car is another subject.

There are 12 different early hemi engines sizes, and yes....they have all been 392's at one time or another.

Now that was the education I was looking for!

I didn't know till today that the last year of it was '58......and I agree, it would seem goofy in my '66 Coronet

I'll always be hopefully I can stumble across a 426 for an affordable price but till then I'll stick with my 383 & 440's

Thanks again guys, Mike

392's are only good for putting in 32-34 Ford coupe's and Front engine dragsters. Everything else is passe'.

They must also have a large roots blower and zoomies.

Any other questions?

one of my friends built a numbers matching 426 where he had to find the block and heads seperately for a 990 64 dodge aluminum race car---he later built a 392 stroker/blower motor for a 40 plymouth street rod---he said he spent way more on the 392 and probably would never build another----if you are building a performance engine you will get more HP/$ out of a 400 stroker with aluminum heads----bob

Actually, they (early model hemis) were still available in trucks through 1959.

Ya but it's a Hemi. I know it may sound superficial and I have a hard running 383 in it now that probably puts out close to those numbers but have always wanted a Hemi and can't afford a 426.




I hear ya. Thats what i'd like to see in my Challenger too. But it aint gonna happen.

What i'm going to tell you though is that if you cant afford a 426 hemi, then you absolutely CANNOT afford a 392/354 hemi. No way no how. Not even close. IF by the time you get that sucker built, even just a typical performance rebuild, AND bolted in/hooked up to your 66 B, if you are not already spending a full 426 hemi budget, then you will be very very close. There are a LOT ov little things that will snag you. EVERYTHING is available, and nothing is impossible with these engines... BUT YOU WILL PAY.

Trust me. Before you drop 2.5K on that whale, understand that you could buy the elephant instead. By the time its running and driving, you'll still be 10K in. Understand that at least with the 426, you can save a LOT ov money with swap meet headers, intakes, aftermarket parts . Plus a lot ov the 426 hemi stuff is also plain jane 440 stuff. EVERYTHING you need came from the factory... (read: there were no 392 hemi's in 66 Coronets)

It sounds like a deal... but unless its already rebuilt, running, and STOOOPID-cheap, AND someone else already spent the coin (lots ov coin...) to mate a modern transmission to it... pass and save for the 426. Unless you absolutely HAVE to have something weird and screwy, let the 3-window crowd have it. Maybe buy it and trade up for 426 parts?

And you still do not meet your real target which is the world famous slightly detuned Race engine which made Dodge and Plymouth the hottest cars in your period of model year. Better start planning/saving to "the real thing", My

Pale Roader: Thanks for the info and advice. I am definitely not going to pursue this or any other 392.

I will safe my pennies and steadily accumulate 426 parts. I'll have to make it a point from now on to get to as many swap meets as possible and just start asking around. Sometimes the best way is the word of mouth

If anyone wants to donate a complete running 426 Hemi to my cause please send to:

Really?? What's the difference if you buy new ceramic headers, aluminum intake, pistons, etc. for a 426 or 392? They both are ALOT. I think the savings comes from the purchase price of the engine. When is the last time you saw a 426 for $2K? You can have a nostalgic 392 putting 425HP for $8K, not a 426.

The difference is what you install it into. I agree totally that the early Hemis BELONG in a pre-64 car/truck, which is exactly what I am building now- a 392 Hemi for a 1947 Plymouth coupe. I am SOOOO tired of looking at 350/350 powered street rods I could puke and the WOW factor when you pop the hood is there ... my

They share the same (basic) block layout, bore, stroke, water pump, distributor,and bell housing pattern. Not much else. Basically a 440 with a smaller bore.

Yep, 426 wedge is a 383 bore with RB's 3.75 stroke. Custom pistons required, cheaper to just build a 440.

At least with a 426 hemi, you can find used speed parts for sale here and at the swap meet, ebay, etc. Used aftermarket intakes, sets of new or used pistons for much cheaper than new, etc. Used 392 speed parts just aren't out there.
