just a note want to replace carb, elderblock, not sure if to use a holley or elderblock. this is a 69 327 from all the castin marks and sn numbers. Also oil presure is bad so will take apart and check bearings, also motor set not run in years, no compression on all cylinders but runs. Bought trk and engine and all running gear connected, misssing the intake and carb, installed them. looks like unknown party was in the process of a rebuild. installed new bottom seals and they looked new as the ones I took out of box. Fired up and run good but shortly oil pressure 5lbs hot idle.
