just had a 460 rebuilt with all new bearings went to go prime it with a priming tool in a drill ccw and i first started with the filter cracked till it leaked out then tightened it up filled filter up but it never built pressure or came out of lifters or pushrods
motor was just running and had good oil pressure before tear down everything was clean. reason i tore it down was to install a cam and heads and new hiflo dynamics oil pump. main bearins and rod bearings were plasti guaged and are in spec i did remove the frost plug on the back side of cam. when i reinstalled it did i possibly plug up an oil gally to the lifters?
