I have just rebuilt a 71 351 Cleveland and need some help, I have no oil pressure on starting, I let the engine run for about 30 sec. And still no pressure, I primed the oil pump and have oil coming up from the rear oil pressure sensor area when I spun the oil pump with a drill prior to starting, but still no pressure, did I miss something, the galley plugs were removed and replaced with new plugs after having the block checked and cleaned. Any help is very appreciated.

 

Sure sounds like it, I'd start by reposting in the right forum or getting a mod to move this. Here is the forum for that engine 335 Series- 5.8/351M, 6.6/400, 351 Cleveland - Ford Truck Enthusiasts Forums
