Low oil pressure?

But what I am saying is that the most push on the crank is when the crank is at a 90* angle from the rod, It may have more pressure on it at a different time like as the fire goes out and the space gets bigger It gets less but the 90* crank vs rod angle doesn't happen at 90* crank rotation from TDC it happens before, not sure if it is at 70* that is why I would have to check on it.

It also depends on the wrist pin being on center or off center like stock 340
