  • 1971 Plymouth Duster Crate Engine Oil Pan
    The engine is delivered with an 8-quart-deep, center wet-sump oil pan that is internally baffled to keep the oil from flowing away from the pickup. It is listed as "fitting most production chassis," so check your application.

    The cylinder heads for the 410 use a 63cc chamber, 2.02/1.60 valves, and have a 171cc intake port. Unlike the '92-later Magnum heads, they use a shaft-style rocker arm setup. If you want to bolt on a set of ball-stud LA heads with the pushrod oiling system, you can do that too. Just be sure to use the correct head gasket with the factory oiling holes.
