Just rebuilt my rst engine using new pistons/oil pump/water pump/shells/bolts/stage 2 head/285t2 cam kit etc. Thought i'd try to build oil pressure by turning engine over on starter motor with no plugs in to ease turning, i also removed fuel pump fuse to stop bore wash but no matter how long i turned engine over ( max 20 secs ) the oil light would not go out. I primed oil pump prior to fitting, dont no whether to risk starting and hoping it will build or what

any body had a similar experiance
