    I know a guy selling a 366 Tall deck motor. I don't know much about these. What are the pros and cons of these. Mods, special parts needed to use one?

    I know a guy at work that has a 366T and he said, "It's basically like a diesel motor that takes gas."
    Very low rpm's (for a gasser) and ALOT of torque.

    GM put these engines along with the 427T's in the "big" trucks ie. 6000 series, and I think even the 7000 and 8000 series although IIRC most of the 8000 series are diesels. My dad has a number of trucks with the 366's, and diesels. It seems that GM wanted an engine that was really overbuilt for durability and not really a performance engine. Look at it as a Big Block 350 of sorts. I have never heard of anyone "building" one of these 366's, but I'm sure it's been done. I have access to a number of these engines and instead I built a 383 SBC. More cubes, alot less weight.

    Finding information about those engines is like looking for Elvis. You'll probably never find anything. I searched before about it for a possible swap, but couldn't find a THING out about them.

    Sounds like they make good boat anchors.

    They weight about the same as a car BB. I have had a 427 tall deck in my blazer for about 6 years now has about 150k on it and runs great. I have blasted mud at 5500 RPM's and has not given me any trouble. I have heard that the 366 are harder to find parts for and like was said the weight over cubes ratio being so small has made the less wanted.

    I wouldn't necessarily say that. Like I said, their purpose is to haul heavy loads and stand up to a great deal of abuse (read: labor/employees that don't give a crap and don't take care of employer's equipment). If you think about what most "Bob trucks" are used for then the 366 is actually a pretty good fit. They are made to work under a load all day, not win any races.

    Sounds like it isn't the motor I want for my K30. Good for a tow vehicle though.

    They did have forged steel cranks that can be put in a standard deck big block, same crank as the 427T. If the price is right you might pick it up for that, forged cranks go for about $600 and up new

    I'd make a tow vehicle out of one if I could find one.

    Not that it provides any technical help, but of note, my neighbor swapped a 366 into his '38 Farmall tractor. Now that's a conversation piece, but it definitely has some guts!

    Is it just the motor? My old lady would shoot me if I brought another vehicle home, lol. Also, it'd have to be closer to KY than NY.

    When I lived in CO, guy that worked on the same job site as me had a mid 80s short box with 3/4 tons in it. Was a 4 speed and sounded BAD A$$!! Not that it had a huge cam, just sounded like it would rip the pavement off the ground. Got talking to the guy, said it was a 366. It wasn't a race motor, wouldn't rev high, and took awhile to get there, but had killer torque. The crank and rods are good to put in a 454 block for a killer 427 motor. Not junk, but for a work truck or tow truck would work good IMO.

    I have one in my 85 dually,stock as far as I know and it runs smooth. It pulls the truck camper well but does not rev worth a crap.
