The KEVCO small block 318-340 6qt oil pan will not fit without modifying the K-frame on the front pass. side. It is listed to fit all chassis that take a center sump pan, but they must not have tried it in an early a. Does anyone know how the Moroso 8 qt 360 pan fits the early A? When I build my 408 I don't want to go through this again installing the engine.
