I have a 350 chevy that I pulled out of a car several years ago. It's been inside and sealed up. When I pulled it it had good oil pressure. I need a temporary engine for my T so I pulled this one out of storage, I replaced the oil pump and pickup and put in a crane energizer cam and lifters (all new). When I went to prime the engine I am getting no oil to the top end. NONE! I looked down in when I was spinning the pump and could see oil moving well, I just have nothing coming out of the pushrods. Any suggestions?
