Update..... So, I took the hv pump off the engine I'm replacing , cleaned and inspected it , then put it on the new engine. Same drill motor, same oil,and the pressure is now is just over 60 psi.
Thanks for your input, I appreciate it.
Changing the pump in the car will be a PITA .I would have to lift the engine to remove it . Would be nice to resolve this issue with the engine out of the car.
That is good news. Do you prefer the number you got with the HV pump?
If it were mine, I would prefer the bigger number.
The only reason I have stuck with hv pumps is...more pressure at idle.
Although I don't feel the engine "needs" it, it's a peace of mind thing.
If you get a chance to prime it with the intake off, even years from now (let's say you decide to try a different manifold later or whatever),
it might be interesting to see what's happening there.
I've found not all lifters are the same size, many are smaller than they should be and they leak.
Sometimes the leak is not 100% negative, for instance when you've got rollers oiled by splash it could be helpful.
