Please edumacate me on INDUSTRIAL hemi's

Found an industrial hemi (Chrysler), but would like to know more about it...

--differences from p***enger car?
--How to ID the year and CID?
--do these have anything cool or valuable like adjustable rocker arms?

Anything else?

 

did you try searching the boards for this subject? I think there was a post about these things in the past month, I'm too lazy to look for it though.

 

Chrysler & Dodge both made different industrial Hemis.
Chrysler block casting prefixes:
331: 20, 20A, 24, 24A, 56
354: 56A
Dodge block casting prefixes:
241: 18, 18A
270: 52
315: 53, 54
325: 56A1

According to Tex Smith’s The Complete Chrysler Hemi Engine Manual, by Ron Ceridono, (which I HIGHLY recommend);
“Unique features include heads, intake, and ignition. Many used solid cams. Some marine engines were reverse rotation for twin engine application. Chrysler truck & marine blocks used the same early style (‘51-’54) front end, while industrial engines may be found with either type. Some industrial heads had cast-in pads for accessory mounting. Some pads were drilled & tapped, some not.”

Mr. Smith doesn't say much specifically about industrial heads which leads me to ***ume they're the same (interchangeable) as p***enger car heads.

and look there, then search the site, there is a better explaination somewhere on it, but I am at work and can't find it. Just realize, according to that Hemi Manual, there was never a 392 Industrial.

Yeah, I am kind of guessing it'll be either a 331 or a 354. Still ought'a be worth picking it up I would think. I know 354's can run really hard with a blower on them.

Hey, is the Powerplay hemi site gone belly up? I can't seem to bring it up anymore...

 

I have both A marine and A p***enger car motor, the marine came with adjustable rockers wich is easily identified by the bumps in the valve cover and also the marine doesn't have water p***ages in the front of the head like the p***enger cars do. I also have heard they never made A 392 in industrial form, my marine is A 58 and is A 354. I have seen industrial heads and blocks used in dragracing where they were hardblocked. not much info here but if the price is right you can always make it work.

Pretty sure that one of the old municipal dump trucks here in my home city had a 392 in it. It was an old Dodge that had the hood and fenders swing away from the body in one piece, must be early 60's. It was a hemi and the old town shop foreman told me it was a 392. When they auctioned off the old stock from the Chrysler dealer here in town, there was a brand new industrial hemi ordered in by the city and never installed. There was some sort of waybill on it that the auctioneer used to identify it and it was advertised as a 392. FWIW, the damn crate engine sold for $250 to some yoyo who intended to put it in his 73 Charger. That was 16-18 years ago and as far as I know, the Hemi is still in the shed at his farm. Maybe the "No industrial 392" rule didn't apply to Canada

 

when i bought mine ,(1954 331) hotheads informed me it was the same as p***, just said industrial on the valve cover mine had the bumps also onthe valve cover heard it was for the adjustable rockers ,which are desireable for running a good cam,only differance was supposed to be the govenor?....

these motors did duty as generators, irragation pumps,ect
