Hi guys. I'm talking to a guy about a 440 engine he has. It's a '71 440 "marine" engine (came out of a boat & still has marine slant-style sump on it) The casting date is 4-21-71 but the engine pad just says "440" not even a date code stamp on it. Does anyone know if Chrysler made all of their marine engines as HP? Right now the engine is still together and we haven't pulled the pan to see if it has 6-pack rods in it. It does have a steel crank though. Any help from the "detectives" is appreciated.

But hey it's Chrysler, anything is possible. |

Remember, the 6 pack guts get the harmonic balancer with the added counterweight on it.
Marine engines are the original severe duty versions of our car engines. The marine parts
bins are where the car engineers went first to beef up their HP engines. I wouldn't expect
anything less than stainless steel rocker shafts & valves. At least that's how my Ford 312
marine interceptor came.

Thanks guys, this will be interesting. I'll look at the front harmonic balancer to look for the added weights and it looks like it might actually have the stainless rocker shafts, I can't really tell but cool! Will keep y'all posted...

Tom, The ID pad IS blank, thought that was unusual as well. Maybe this was a warranty block or a boat thing? I've done a little sleuthing about these "marine" 440's. Some of them were in fact reverse rotation "right hand" engines, to counter prop walk in twin engine setups. The cams on those are apparently really rare and go for $300 or so used, if you can find one. I don't know if those is one of those kind of motors or a "regular" one. When I pull the cam, I'll compare it to one of my regular ones to see. Unless you're a boat person, what in the hell do you do with one of them? The cams looks good, in fact the entire inside of the engine looks brand new, no sludge build up at all anywhere except some glop at the bottom of the pan. This motor was a Hurricane Ike "survivor" and in a boat warehouse that had some minor flooding. This engine was on a stand and I think the water came up to right at the oil pan level, but not above. When I pulled the drain plug, I got about 5 quarts of clear water out with little/no oil, kind of curious. Finally, the 452 head looks like it had a machine shop-installed valve seat on one of the exhaust valves. Interesting as I thought those factory induction-hardened 452 seats never wore out...

. See attached pics. Got the heads off (mismatched, one's a 906, the other a 452). Some observations so far: No stainless rocker shafts/hardware, looks to be basic "car stuff". The oil sump is cast aluminum, not steel. with baffles and windage tray. Steel crank, but not 6-pack (standard LY rods) with 3-bolt cam. Oil pickup is an interesting piece. It has a "swivel end", allowing it to pivot up and down about 20 degrees each way from horizontal. Also interesting is the factory-looking distributor "insert" that fits into the distributor hole. It has a part number and an o-ring, doesn't look to be homemade. The final upshot is that it's a '71 440 block/crank and that works for me...
