there used to be a boat building business in my area".Leecraft" they used to put yblock 312's in their inboards.I saw one recently and it was beautiful.the sound of that 312 was really sweet.they were manufactured in the late 50's and early 60's.I've run across several that have been junked out but wondered how those engines would be in a car.

I have a 63 marine short block in my truck. The water jackets were severely filled with crud and took a lot of flushing. You can't easily use the timing chain cover oil pan or ex manifolds and the intakes are weird and expensive to get working.

Some marine engines run backwards, which won't work in a car. I think they were from large boats with dual engines, one forward and one backward rotation to counteract torque.

most marine engines were 292's , the intakes are a little small ,but use 2 side draft ,1 barrels, they look really cool in roadsters account ,everything is below the valve covers. The front covers are really nice to use for front cam drive pieces, marine cast aluminum oil pan also has possibilities. Once these pieces are gone, they won't be coming back !

Tim and guys, i can add a story on one of these interceptor boats, here in Sydney during the 60,s onwards there was a twin interceptor engined boat used to take tourists for a cruise of Sydney harbour and across the other side to the amusement park, like Coney island. It eventually saw its days out hanging of a mooring near local boat shop and ferry wharf. i heard of it and found it had finally succumed to neglect and sunk, it had been dragged to a little patch of sand near the the wharf and everything but the 2 engines were scrapped. i headed down there with basic tools and asked owner if i could take any parts from the engines, ok! only problem was they were covered at high tide, so working in knee deep water i got the intakes and other uncorroded parts, i then organised tow truck next time to pull them up the wall and onto dry ground but they were removed during council clean up! dang it!. often the twin engined boats had one counter rotating engine turning in opposite direction with a gear driven cam, they had mallory distributors, great valvecover with oil filler cap, they had no rubberised harmonic balancer but solid one like early f100 truck, i guess the prop shaft got rid of the engine harmonics, they came in 292 and 312 and were made by the Eaton corporation. I do have the workshop manual on them if i can find it. best regards bill.

Just by coincidence there is a seller on Kijiji in my area parting out a 312 interceptor motor.No block.He has the aluminum intake with carbs asking $275.00.Are these carbs suitable for car use?Do they have the same accelerator circuitry as the car carbs.Just curious.

Those could work ok in stock daily driver, but might be small on Hot Rod usage? 
Set up is very low, so it fits anywhere.

That is excactly the setup being offered for sale.I am thinking about buying it and using it at some point for mine which is stock.They are single barrel carbs are they not?this guy has the manifold and linkage complete and everything moves freely.These manifolds are aluminum so he tells me.Much lighter than stock cast iron.jWhat do you think of asking price at $275.00?He is also going to email me pics od the rocker covers.Says they are chrome with some spots of rust.I dont know if they are stock or afterermarket yet.

The carbs are 1bbl and the same as the Blue Flame vetts. Not big on power but will run. The 6 cyl vette had 3 of them. If you buy this intake make sure you get the water inlets for the heads. They are two seperate pieces held in part by the front intake bolt. They are where the hoses attach in your picture. Without them you will have to fab up water inlets. Chuck

I see the hose on each side going to the water manifolds.What would you have to do to use this setup in a car?How would you install a thermostat and the hose to rad?
|

you will also have to have the special valley pan to clear the bottom of the intake.
|
|
By MoonShadow - 14 Years Ago

You would need a y connector like Smokey Yunnick used to make. Or plumb the radiator for two upper hoses. If you have the adapters there are several ways to do it. I'm not sure about the thermostat but you could probably put a restrictor in the hose connections to slow the water down. Basicly a washer that fits against the cast outlet with a large center hole to let water pass through. Chuck

Thanks! He has the valley pan also included with the intake price.Is this idea doable without a LOT of problems?With the automatic trans I will need to find a way to mount the bellcrank assembly on the manifold.

More info from the seller on Kijiji.The motor was destroyed and scrapped years ago when when the camshaft broke.Supposed to have been low hours.He has the heads supposedly undamaged and the chrome rocker covers which are needed when using that intake because they have the oil fill opening.He sent me pics of the covers and they look pretty good.Couple of rust spots on them but useable.As well he does have the water connectors for each side of the manifold.Are the heads of any value being 312?Any input from anyone?

Its not uncommon to find good heads on these boat motors. Check them for ECZ-G or 113 markings under the casting where the water inlets bolt up. If they are unbolted just tip them onto the exhaust manifold side. Chuck

Very nice.Those intakes are aluminum.Would look real sharp polished but I guess they were painted originally.

Mark, those sidedraft Carters are the same carburetors as where used on turbo Corvairs (Spyders). Should be able to get kits for them at a Corvair restorer. Clark's comes to mind.

I just got back back from checking out the marine stuff.The heads are ECG-T which apparently are cast for marine use.Small 1.78 intake valves.That casting # does not even appear on Mummerts site.Interesting distributor too.Mallory dual point but no advance mechanism which I guess you dont need on a boat motor.Showed me whats left of the camshaft.Apparently this was a rebuilt motor and didn't last too long before it desintegrated.The valley pan is also aluminum with spark arrestors on each end where the carbs fit into.Brass trim on the arrestors.The carbs and linkage are complete and move freely.Need to redo carbs obviously.He will take $275.00 for the intake setup with valley pan,water connectors, and chrome rocker covers which are a heavier steel stamping like regular factory covers-just chromed.The oil pan is interesting.Just a big square aluminum box-no sump like cars have.I am seriously thinking of buying this setup and make it a project down the road sometime.Any input from anyone?Is this price reasonable?Is that Mallory distributor of any value?He wants $40.00 for it.

I never looked into the boat Mallory's but do they have a centrifical advance? Not sure. If you want to get the oil pan you will also need the front cover. Its much smaller than the regular one. These oil pans and front covers end up on a lot of dragster Y's and work well there. They could be used on a car motor but would take some fabrication for pullies etc.. Also the damper is usually a small, short one that ran only the alternator. Behind the damper is a spacer that moves it out to the correct alignment. I use the spacer with an old socket welded on for a crank turner. Works great, and uses the stock keyway. I've seen a few of these on hot rods, especially ones with low hood clearence. I have also seen them polished and they can look very good and unusual. Only the real Y's guys know about the boat motors. Chuck

I am not interested in the oil pan etg.Just thought it was interesting to see how different it was from passenger car pan setup especially being cast alumminum.I would assume there is a centrifugal advance in the distributor.Has to be for it to work properly.Trying to decide if its worth buying and maybe resell and cut my cost for the rest.

Parts are now listed on Ebay under "Ford Y Block".He is asking a lot more now than I can buy them for.Any comments?

If your not in a hurry I would wait a while. Check older local boat yards etc.. The last two of these I got were free for the removal. These parts seem really high. Chuck

You are referring to the intake manifold and rockers I assume?He was asking $275.00 OBO.I was really not sure what they were worth so I did not go any further than having a look at them.Interesting items.
