Mopar Muscle Association UK

Good evening all.

Whist wandering around a clearance yard a V8 engine got my attention. (As it would with anyone with a pulse!)

Due to the lack of Ford or GM markers I made a guess on a Mopar. After looking online, my suspicions were found to be correct. I returned today to try and get the block casting number but have not been able to find it. Now, to be perfectly honest, A/ I did arrive 15 minutes before they closed, and B/I was still not sure I was looking in the right place. I did mainly look at the left side of the block but could not find it. I did expect to see it lower left at the back? (See photo.) If that is where it's supposed to be, then the block looks like it has grinder marks in this area.

I was told that the engine arrived 5 weeks ago and they knew nothing else about it. (They did not even know the make.) The exhaust manifolds have tape over the ends, the distributor hole is capped and the paint on the front pulley has not worn off. The oil cap seal is old, but inside the oil filler/rocker cover is totally clean. This would look to me like a rebuilt engine.
The engine looks like its been in the wet due to the localised top end corrosion. It will also not turn over and due to there being two bolts handily fitted in the end of the crank, someone has been there before me.

There is a casting number on the inlet manifold, 2284863 (or possibly 883?) I can not find any match on this number on the casting reference lists online. The left exhaust manifold has 2264192 also no luck but an old parts supplier listed it as "Dodge 413" with a part number change to 1936589.

Can anyone give me any help with the exact block casting/engine numbers? Or, with the other casting numbers I have?
Failing that, would it be best to pull a rocker cover off and get a head casting number?

Thanks for reading. All suggestions greatly received!

The internet says this below is a 413 big block

the water pump holes?? look to be the same, the timing cover looks very similar and the timing tab is in the same place
doesn't mean you have found a 413 but it seems you are on the right track.

i think you found an early big block at least
common or garden 2bbl or 4bbl
i.e not interesting inlet manifold, or manifolds on it

if it is 413 that's an RB engine from 1959 onwards

if it was a 2bbl its a school bus or truck engine
can't tell if thats 2bbl or 4bbl inlet

it doesn't have the 2x 4 barrel 4BBL inlet, or the long ram 44bl x2 inlet which would make it a truly interesting piece especially to a person owning a car that was its orginal resting place.

Yes most likely a 413.
The horizontal pad across from the dizzy hole designates it as a raised block (RB). This should have some numbers stamped on it.
Therefore 440, 413 or 426.
But the early 4 bolt valve covers rules out a 440.
And it's unlikely a 426 with a 2 barrel inlet, which is what it looks like with those 4 carb studs so close together.
As Dave says they did fit those to all sorts of vee-hicles so maybe a low compression bus motor.
