    They are quite a bit bigger than their automotive engines.

    I've thought for years that you could build a cool street rod with one.

    I was always under the impression the block size is actually the same.

    Come on all you Lambo experts,....what's the possibilities for these engines??? Seller says that the cylinders have light corrosion. I can't believe that a sealed engine would have enough corrosion on the cylinder walls to demand a complete rebuild. Unless they've been under water, the cylinders should have been completely sealed. (Unless somebody left the spark plugs out and the cylinders filled up with rain water. Ouch!)

    If their saying "light corrosion", expect worse.

    On any engine, several valves are always open when stopped. It probably was stored near the ocean, salt air, guess the rest. If they were ever in a boat the block could be corroded inside the cooling jacket from salt water.

    These engines are built with either clockwise or counterclockwise rotation. You would need to be careful or your car would have 5 reverse speeds and only 1 forward.

    With a displacement up to maybe 9.4 liters (not sure which these are) and a redline near 8 grand you could leave that pesky Viper in the dust.

    They look similar to the automotive engines but there are bound to be a lot of differences. A fun engineering project for the resourceful.

    More than likely they were exposed to a salt water environment and did not have a closed cooling system. If that is the case, I wouldnt even entertain making an offer. My boat mechanic has told me that marine engines have the same components as car engines, only the tolerances are not as close in order to compensate for the time these engines spend in the higher rpms. They would probably make some cool furniture.

    Some Chrysler and Dodge marine engines were built with reverse rotation in the 50s. As you say, you have to be careful and realize what you're getting. I assume that a reverse rotation engine would require a change in camshafts because the lobe ramps would be different in order to convert to correct automotive rotation. (Unless the lobe ramps are symmetrical...) What are the camshaft profiles like on an automotive Lambo engine? Are the UP ramp and DOWN ramp cam lobes identical???

    Cam lobes appear pretty symmetrical but they would be completely different as far as timing. Chain tensioners would probably be in different places because of the reverse rotation. There are other more subtle things that may be different as well for reverse rotation (oil pump would have to be different).

    Don't most racing boats use 2 engines that rotate opposite to EACH OTHER in order to counter torque? If so, at least one of those engines would probably be the same rotation as a car.
