couldn't wait any longer! took car out today

Im going to wait just a bit longer, I figure this is a good time now the temp has got over 0 to start doing some of newly planned work. A 3:73 rear end, roller rockers, and a port match on the intake and exhaust. Oh and find out where that leak is comming from. Is it the oil pan gasket or the rear main seal. I hope its just the pan.
