I recently acquired this engine, but I haven't been able to find much information about it. From my research, I believe it's an industrial engine. It has the numbers 2899830 on the block and 2806 887 on the cylinder heads. Can anyone provide me with more information?
Discover engine model. Help!!

Block casting number 2899830 is for a 361 industrial engine beginning in 1968 and used into the 1970s.
Head casting number 2806887 was used in big block marine/industrial applications including the marine 426 wedge engine.
Not saying you are wrong, but I looked at several sources and came up with a '70 383.
It would make more sense if it's a 361 block with those industrial heads though.

I've seen lists containing the lone 1970 383 entry for this casting number. It is apparently an erroneous entry. The last block casting for the 383 is number 2468130 from late 1964 - 1971.
The source of the number was likely a simple mistake, misidentity or perhaps a modified/over-bored block that was misidentified by measurement, then the 2899830 number was entered into a list. The list, in turn, has been copied and re-copied, as is often done with things, particularly online and without attribution, so the error propagated.
I wouldn't rule out any possibility, but it seems unlikely to be a 383. More details about the engine, particularly any stampings would tell more.

Yes, reverse rotation big blocks were available for the counter rotating half of twin engine installations.
I agree that it could possibly be an error that's been copied and pasted several times. I see that with some other info, like rear end widths, that just goofs it all up.
I'd say that more info, like some good pics of the stampings will really tell the tale. The industrial heads point to a stationary/marine/RV/truck engine, so the 361 makes a lot of sense and I think that is the case. It's worth looking at the crank flange too.
At least we are in the same B-block family. LOL. Ultimately, pulling a head and measuring the bore will give the answer if there's no good external ID.

I believe there were 2 actual industrial motors. The 361 and the 413. There were some different 440 combos for motorhomes as well.
Looks like freaking Alexa was reading my mind when I saw your post.
This popped up in my FB marketplace when I was looking at another car.
440 Chrysler big block
Big Brother is watching you lol.
So, for $900 bucks, some folks may think they are getting a steal for a good bottom end. But heres the question.....you can see the obvious marine stuff is of no use for a car application, but how much inside is useless?? Cam and distributor, along with oil pump drive im guessing. So, you would assume good block, rods and crank......BUT, would the crank not have the rear seal oil control knurling (knurling not the right term) cut the wrong way??? I would think that thing would actually push oil out like theres no tomorrow??
I'm not sure if you can use the crank anyway. The rear flange may be different and then there may be gears instead of timing chain.
Everything may still be usable for a car... I don't know, but IMHO, figure that just the block is usable... But if you're building a stroker, the block may just be all you need.
That's not a marine engine, so it's extremely doubtful that it is.
