The heads are a dead giveaway on a Chrysler industrial engine versus a regular Mopar engine. The front ends of the heads connect to the water pump housing and the spark plugs are located above the exhaust manifold (like a small block Mopar engine). The big block industrial engines have the distributor up front like a normal Mopar big block and only came in 2 sizes, a 361 and a 413. The easiest way to tell the two apart is by the flat machined surface behind the water pump. This pad will only be on the 413. The trick is the higher water pump used on these engines make it harder to see this area clearly.That's definitely a Mopar big block. It's hard to say from the pics which one it is. If it's a raised deck (RB) big block it will have a flat machined surface about 2" square right behind the water pump tot he drivers side, even with the intake mounting surface that will be stamped with the size and other information. The common RB series engines are the 413, 426(wedge and Hemi) and 440. If it's a B-series or low deck big block, the machined surface I mentioned for the RB series will not exist. Instead the information will be stamped just to the driver's side of the distributor, sort of behind it on a pad machined even with the passenger side head surface. Common B-series low deck big block engines are the 350, 361, 383 and 400.
Could be either a 361 B or 413 RB engine. Both engines used the same heads and water pump housing. The baseline 413 industrial engines used in trucks came with a 2 barrel carb (called a 413-2 engine). The top of the line 413 (called a 413-3) came with a 4 barrel carb. The industrial engines used in RV's had 4 barrel carbs. All industrial 361 engines used in Dodge trucks had a 2 barrel carb. it was the same size (500 cfm) as the carb used on the 2 barrel 413's but had different sized jets. The 361 was used to power the V-100 armored car but it came with a 4 barrel carb. Both the 361 and 413 were used in Dodge heavy duty trucks all the way up till 1977 when Dodge stopped producing the D700/D800 series of trucks and dropped out of the commercial truck market.If the water pump housing mounts directly to the front of the heads, it's most likely a RB series industrial engine. These things are easy to identify if you know what to look for but unfortunately none of the pics clearly show these identifying areas. The intake and carb is making me want to say it's a low deck B-series engine, but some of the industrial RB engines did come with small 2BBL carbs so it could still be a RB engine. The 413 and 440 industrial engines were in production through the '78 model year, the 361 and 400 versions were dropped much earlier.
You are mostly correct. Mopar industrial and marine engines were offered in all of the common sizes, both small block and big block. The 360, 361, 413 and 440 were the most common.
You are correct that not all Chrysler industrial engines came with the odd water pump. My comment was aimed at 361/413 engines used in Dodge trucks. On the industrial big block engines that Dodge used in their medium and heavy duty trucks I have never seen a 361 or 413 without it or the different heads meant to be used in conjunction with the higher water pump. I may be wrong but out of all my manuals I have not come across the use of anything other then the high water pump and heads on 361 and 413 powered Dodge trucks.Not all industrial engines came with the odd water pump housing and heads though most of the medium truck engines apparently did.
The 318 commercial engines used in the medium duty Dodges were like that. There was only some minor differencies between a car engine and the industrial version. And yes, Dodge did a lot of unusual things over the years but most of their industrial gas engines pretty much stayed the same in regards to the use of them in trucks.Some engines were just low compression heavy duty versions of regular production engines with few changes from the normal car and truck engine. I've enjoyed your page on Dodge medium and heavy trucks and the brochures are especially interesting but with Mopars, nothing was ever set in stone and there are a lot of unusual things out there.
I would disagree. I have seen several RB engines with 2BBL carbs. [FONT=verdana, arial, helvetica]007 is the fender tag code for a 413 2BBL engine in '64, [/FONT]082 is the code for a 426 2BBL engine in '64 and '65. Also, early '60s RB engines did come with 4 bolt valve covers. FelPro still carries the gaskets for them. The original Max Wedge engines had 4 bolt valve covers.it is a 361 dodge v8 big block
4 bolts on valve cover means 361
no 413 426 or 440 ever came with a 2bbl carbatooter
so it is 361
FWIW. Maybe the EARLY Max Wedge engines came with 4 bolt valve covers but not all of them did. I have a set of MW valve covers on my '70 440 pak right now and they're 6 bolt and fit fine. I use those on my car because they had the brackets where I wanted them. IIRC they came off of a '64 MW.Also, early '60s RB engines did come with 4 bolt valve covers.

Hey Hoosier Boy......it's spelled D-E-U-C-E !!!!
Perhaps, but I would hazard to say that most Max Wedge engines had 4 bolt valve covers. The originals did for sure and I have seen several Stage III 426 engines that still use the 4 bolt covers.FWIW.
