Guys I just put 383 in my roadrunner. I bought a rebuilt engine from a Mopar guy never ran. Stuck it in but had excessive valve train noise. Took valve covers off and heads bone dry. I took off sending unit and primed motor w drill and oil comes out but does not shoot out like I'm used to. Put auto meter gauge on and pretty much reads 0. Bought new hv oil pump thinking it was just bad and still same result. I'm at a loss. We yanked oil pan and pickup looks new and is clear. Nothing obvious as we looked at oil pump passage where oil pump goes and everything seems fine. Everything in motor is brand new and I've been up and down it now. When I start it , sounded good from back end other than valve train. Makes me think lower end is getting oil. I'm clueless and at odds on what to do next. Any engine guys ever run into this? Need help fast
