What the heck am I doing incorrect, bring #1 to tdc, apprx 18-20 degrees on balance, drop in disy, it drops into intake rubber seal in disy is down into intake apprx 1/8 inch, pulled and rotated oil pump drive, reinstalled, seems like disy is not dropping in enough to enguage oil pump drive, I am using an ARP one piece drive shaft from oil pump, when I installed it motor was upside down on stand, put shaft in with small retaining washer pointed towards top of engine then installed oil pump. This my first Ford project
thanks for any info or ideas
