413 marine industrial (E) engine, to, not so industrail......

I have 2, 426 wedge marine engines. These are cooled by water with seawater intercooler. The water pump has more fittings than fleas on a dog. They also have a cast aluminum oil pan with swinging pickup. I have seen 392 Hemi, 426 Hemi, 318-360 wedge and /6 marine engines, both standard rotation and reverse rotation. The reverse rotation engine cannot be used in standard and visa-versa because the stryations on the crankshafts rear seal is directional. Used incorrectly oil will be pumped out of the rear seal. To solve rotational problems one engine has a reverser which offsets the other. 915 and 516 are closed chamber heads. Used in marine service they have exhaust valve rotators. 413 were used until the early 70's in marine/industrial/motorhome service. All 413's have steel cranks and internal balance. Hope this helps, Tom
