360 BALANCING

Then engine had a fresh rebuild when i bought it I bought a flywheel that came off a 360 engine. When i had it running without the super charger it ran smooth and no oli leaks. I put the super charger on then it shakes and im chasing oil leaks. I notice thatv the rear main seal is leaking know. I stuck my hand up and turned the throwout bearing and it skweeked . Its just barely riding on the clutch.
