Completely differwnt engines but a 392 is a great engine.Whats A "good deal"? Better be sure its a 392 a lot of lesser 50s hemis look alike.
I guess a "good deal" would be $2500-$2800? I have never bought a 392 before and honestly can't afford a 426 so I figured a 392 would be the next best thing. It would be going in my '66 Coronet Vert. My car is far from stock, more like a resto mod

The 392 is a raised deck version of the original Chrysler Firepower Hemi and as such has bore spacing 4.5625". It is a lot closer in design to the A/LA engines than to the B engines. A 426 Hemi is an RB engine, that's a B engine with a raised deck. Bore spacing is 4.80". The only thing the 426 and 392 have in common is that they were based on a raised deck version of a previous block series, and that's a words-only similarity. The other major pitfall for you and this engine purchase is that from the outside it is very hard to tell a 392 from the much more common 354 or 331. There is a code I believe stamped onto the top valley rail that will tell you what the engine is and where it's from. Do a Google search for Chrysler Hemi and you'll find the chart. Lots of information is on the Web. Now on to this particular engine - once you determine that it's a 392. Here are my top five reasons to buy a 392: 1. It's one of the coolest looking engines ever made. 2. You own an early letter series Chrysler and want to give it a boost in power. 3. You have a nostalgia dragster and need a 392 to make it right. 4. You have a spare '34 couope body lying around and want to build a traditional hot rod. 5. You have a big wad of cash burning a hole in your pocket and you always wanted a Hemi. If you want to see what it would cost to rebuild a Hemi go to PAW or www.hothemiheads.com. They ain't cheap! For $3000 this engine would have to be guaranteed to be rebuildable, like pass Magnaflux and crank and bore sizes are within reason. Even a fresh rebuild would need to be gone through because there are good parts and crappy parts..... Also I think that price is more of a speculative price, much like the $2500 barn fresh DeSoto or Dodge hemis I see on Craigslist every now and then. Good Luck! R.

Was '58 the last year for the 392? Looks like they put out 390hp and 435 lb-ft. That would make my Coronet scream!

You can get that out of a 440 for a lot less money .

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 just recently picked up a 2003 5.7 Hemi to do a conversion but am having second thoughts. I really like the old school carburated BB's though

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.

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?

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

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?

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 
'70 Cuda "Badfish 2"- in the works

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.

Ah no, I was referring to a 350 B motor In 1958 you could get a 350 . Now that's an attention getter and an argument at a car show   
Aaaah, I thought you were talking about a Chevy SB and was stirring the pot!

Hah! Are you kidding...??? Whens the last time you ever saw a late-50's Mopar 350 big block for sale...??? Probably find a cheap hemi before a 350 turns up for sale...
Points for being different though.
Double points for confusing the hell out ov the Chevy guys too.
Triple points for confusing a Mopar guy...
