Hello all! My name is Nathan, 21 years old, and this is my first Y-Block build. I stuffed this engine in my little '31 Model A coupe my dad and I built together. I have a 1960 292 block, bored .060 over, off set crank ground to the 312 stroke (314ci). 11:1 compression, cam is a clay smith cam, 240 duration @.050 and .485 valve lift. '57 ECZ-G heads. FRESHLY BUILT ENGINE. All new parts from John Mummert. Only have close to 2,000 miles on the car. Anyway...

Seems to be when I come to kind of a hard stop (I'm not locking the tires up) or make a hard left turn the oil pressure drops down to around 10-20 psi then jumps right back up between 50-60 psi. I am honestly not sure if this is a new occurring thing or has been happening but I just noticed it. I watch the oil pressure gauge like a hawk so I'm surprised if it had been happening and I haven't noticed it. before. Course typically when you're coming to a stop or hard stop there is a reason and you're paying attention the road haha. I'm running 10w-40 high zinc Royal Purple HPS oil. The oil level is good, and the sending unit isn't bad, those are the things I checked first. I have a rear sump truck oil pan on the engine. Is this a normal thing? Should I be concerned? Obviously the oil is going away from the pickup when I make these actions, just wondering if something possibly fell off the pickup?

Thanks in advance for all the advice!
