Yesterday I bought a 318 "Smog" motor as it was advertised. I bought it for the peripheral parts only, brackets, valve covers, and such. The engine was complete with transmission.
This morning as I was disassembling it I started checking casting numbers
It caught my eye because of the four barrel carb. The manifold numbers show that it is a 318 four barrel.
It is a February 1981 318. When I looked up the casting number it came back as a "Race Engine". What is this? A cop car engine? Any help would be appreciated.

no idea but I'm really curious to find out now. haha I'll bump out of curiosity
 
It's a smogger 318 with a 4 barrel. So if being more performance oriented having the 4 barrel, then OK.

The same casting number was used on race blocks, which that one isn't.
 
Same thing was asked in the past. Here is an old thread. Basically, they appear to have used the same casting # for std. 318 blocks and their race blocks at that time, which started out with a 318 bore size. But there were added differences where you could tell which it was. That is a std. 318.

4 bbl 318 have 360 intake and heads other than that nothing special.
 
I'd say that the cop engines came with 360 heads and a 4 barrel, but it looks like it has a truck oil pan on it.

Did you score the 727 with it as well? Is it a lock up or non lock up?

The 727 came connected to the engine, just like it shows in the photo. I don't know the difference or how to tell between lock up and non-lockup.

Flat pistons
Crankshaft is 3751841
Intake manifold 4173915
1.88 intakes
1.60 exhaust

Nice and clean inside. I don't have a great measuring device but doesn't appear to have been previously bored.
Just a good 318 with a big top end I think.
Going to find it a good home with somebody else. I don't need the engine or the transmission.
 
When you separate the transmission, remove the torque converter and look at the input shaft. Non lock up shafts are splined right to the forward end, lock up shafts have a pilot area forward of the spline much like a 4 speed input. I would guess, being a truck engine / transmission that it is a non lock up and a good core.

360 heads and intake on the 318, all AHB M bodies were built like that unless it was a detectives car

What? Sorry, but explain this to me, please.

I've seen plenty of plain clothes AHB M-bodies over the years, never badged, which still had the 318-4bbl.

I've also seen AHB tagged M-bodies with slants and 318-2bbl's. Those were badged and wearing municipal colors.

The cars were ordered in batches and assigned duties from there for the larger orders. Smaller municipalities usually piggy-backed a car on larger state orders to be able to get the better buy-in.

So what defines a "detective's car?"
 
Here's a chart most of you have probably already seen but I thought I'd throw it in here since there's a cylinder head number mentioned. I see a 402 number in the 360 section that looks close.

Cop engine also had a windage tray & double roller timing gear/chain set up along with the 360 heads & intake.
I had pulled one from a 1985 patrol car & installed it into a 1979 Volare.
This engine really woke up with a Thermo-quad & regular electronic distributor.

I bought a new Dodge truck in 1982, it had a 318-4bbl engine in it.
This was the upgrade engine for 1982.
Never had it apart in 175K miles, but probably didn't have a tray or double chain in it.
It did have a lock-up 727.

MoPar went to painting their engines Black midway thru 1983, they were Blue before that.
 
They changed to black to hide all the oil leaks.

okay, sometimes detectives cars only got a 318-2 or sometimes city police only got a /6 engine, there is no rhythm nor reason why anything was done at that point in time
