383 stroker rear engine seal leak.
looking at buying a 78 camaro with a 383 stroker crate motor in it. car is in great shape but the rear engine seal is apparently leaking and needs to be fixed. could this be anything else and is this a big risk purchasing the car. i know that just fixing the seal is an easy fix but could it be something else that might raise concern? thanks and the engine has 20k on the rebuild
