Default 1979 318 4-bbl police

I recently lucked into finding a rebuilt low-mileage factory 318 4-bbl police engine. The motor was in a 1977 1/2 ton truck. Here are the specs that I know of. Stamped on front drivers side of block below the head is 9M-318 1008127 It's a thinwall design. There are no numbers on the passenger side oil pan rail. There is a pad roughly 2" wide, but nothing on it. Same side of the block is cast 8-23-1978. On the other side of the block is the 318 casting number designated for 1979. And that's it , except for the date clocks. The heads are factory 4-bbl for a 1977-1979 with small chambers, small ports with 1.88 and 1.60 (360#s). It has the 360 4-bbl cast-iron manifold that accepts a thermoquad. Came with 360 exhaust manifolds. The crankshaft is drilled and ready for a bushing. (the truck was an automatic) Now for the questions. Is there a special head gasket needed for this particular application. Does anyone know the true hp/torque for this engine, I've seen many different figures. Anyone know the cam specs or a suggestion for a rip snorter street racer 65 cuda. Did these police engines come in the super coupes and the petty race package cars for 1978 or 1979. Thanx for your time.

UGH! I pack away my books so this is from the gray matter.
Any early head gasket will work. Just go to Ma Mopar for the correct thickness and pattern of holes for the heads. later years came with more holes. I was told there for cooling. I don't know for sure.
Fel-pro, and others have gaskets @ about.040 thickness. This is about twice the thickness as stock.
HP figures escape me for now, but, the were low due to the way the were read. (All acc. on and running etc..) I think it was 230 -250 hp.
Hmmmmmmm, a "rip snorter " cam. I can think of a couple that will do the trick. Problem here is, I don't know what else you have in the car or what your truly looking for.
Whats rip snorter. Sounds like the back rooms before, during and after high school. Also every Fri. nite to Sunday afternoon. (Only kiddin ya)
To me, 300 hp is a base level hp for all my rides, a fun level of HP is 400+. A kick a$$ power level is 500 + with a 200HP No2 shot runnin down the back roads. With or without the bet.
Tell us your idea of power and the rest of the drivetrain.
We'll hook you up!

Default Police heads (360)

The special police head was introduced, in march 1977.This new casting added more water jacket holes, in the lower edge(spark plug side) of the cylinder head. these extra holes are for sand removeable only. They do not affect water flow or cooling. For identification purposes, the older police heads had4 D shaped holes, while the newer have 9 triangular-shaped holes. The new head uses a new production gasket (pn:4027329). this gasket can be used with the older heads, but the older gaskets cannot be used on the newer heads. Just for info, and i quoted this from, my "How to Hot Rod SMALL BLOCK MOPAR engines. By Larry Shepard. I bought this book @ Summit, in reno, nevada. It covers 273-318-340-360-cids. Hope this of some help Don

Don/concord997;

I remember reading somthing like that now. Do you know why you can't interchange the 2 gaskets? I have that book as well. Good reading that book even though it's a few years old. I would recomend that book to anybody looking to turn it up a few notchs in the HP department.

Default head gaskets

Howdy Rumblefish360, I don't recall the reason, for interchange, between gaskets. I don't remember reading about it, in the book. Maybe, it's the difference between the triangle shaped holes and the 4 D-shaped holes...???? This the best book i've found on the small blocks. By the way, witch set of w-2 heads, are the best, for an engine, i want to put together. I'm just gathering info, for now, but i'm hearing about these w-2 heads, etc.. 202s will be a necessity. Til later Don
