D0VE-A block

I bought a 460(?) today. I am not familiar with these engines so I have a few questions.
After a quick check I found a few casting numbers which are really strange.
This engine came out of a 7x motorhome (according to the seller)
The block casting number is D0VE-A and I found a small 460 casting on the lower front area.
The heads have different numbers. One of them is D0VE-C and the other is D3VE-A2A
The seller said that they have measured the ports, valves, the chambers and they are same. Is that possible? If I remove the valvecover can I find things ( for example valvetrain) which are identify the '73 and later heads and '68-72 heads?
The intake manifold castings start with D9 and the timing cover with D2 letters.
Any idea?

D3 and D0 header do not interchange. The D3 heads have much larger chambers.

So the best way would be to remove the heads and double check them? I have just checked the exhaust side because there are no exhaust manifolds on it.
From the exhaust side they are exactly the same.

You should use either on casting or the other. Compression will vary about 1.5 points from the d3 to the D0. And if the valve trains are factory, each will have different type rockers.

I will remove the valvecover tomorrow. What if they have the same valvetrain? I am pretty sure of that seller is not that stupid to use different heads. He wanted to put this engine into his '71 mach1. Unfortunatelly he got financial problems, that is why he sold it.
Is it possible that only the casting wrong,and they are really same? As I know there was a big chaos around that era with casting numbers.

No its not possible if one is a D3VE (92cc) and the other is a DOVE (76cc)

unless your reading the number wrong.

I decided to take apart this engine yesterday and I really surprised of what I found inside.
4 bolt mains... what the h...??? what car did this engine come from? Not from a motorhome as the seller told me for sure.
I collected all the casting numbers I found. Here they are:

Block: D0VE-A 4 bolt mains, CJ 3 or CJ 8 casting in the oil valley above the date code, date code is 0L18, scratch mark on the back ( same as on the 428CJ block) looks like "t" or "c", stamped number on the back 1A185790, 460 casting mark on the front and on the back

Main caps: starts with C9AE (for example main cap #3: C9AE / 6330 B )

Rods: D6VE-AA , rod caps: C9AE-B

Piston: 50 460

Crankshaft: 3YA

Can somebody help me to identify this engine/block? I am wondering maybe this is a 429 CJ/SCJ 4 bolt Block.
Thank you.

Sounds like you ended up with a SCJ or Possibly CJ or PI 4 bolt block.

Post some pictures up we'll give you a 100% ID on it.

Yep thats a 429 SCJ / CJ / PI 4 bolt block with a later 460 rotating assembly in it.

Thanks. All of these engines use the same block?
Does this stamped number tell anything?
1A185790

SCJ's where supposed to be all 4 bolt's, CJ's a few and Police Intercepters, Some to most.

Thats the VIN nunber of the car it came from, should be a Torino or Merc

Thanks for your help

Nice.....

What about the heads, what is your findings there?

Btw..how much did you pay?

One more question please. What about those 460 marks? Is that normal on a 429 CJ?
