So this customer comes in with a 383 sitting on Schumaker motor mounts in a 74 roadrunner that was originally a 318 car. Any how the motor will not sit down in the mounts because the oil pan is crammed up against the front of the oil pan, the front of the deep part is sitting on the rear edge of the k-frame, we loosened the trans mount and moved it as far back as possible and seems like we need another 1/2 inch. Is there another pan we need to put on? Mabey there is enough production tolerance in k-frames that it won't fit in some of them? Mabey the mounts are just junk and don't work
