That's awesome, buddy! How was the 60' and what converter and gear is in it?

I was having some oil pressure related issues as well, not as extreme on the low side ( never got below ~37 on the gauge) but I've already found a couple ways to pick it up, in my case it's not a pump delivery issue but a combination of a line side flow restriction combined with too many leaks downstream. The combination of porting the AN fittings going In and out of my oil cooler and inserting a rocker shaft restrictor bushing between the 5/16 shaft stud and the 3/8" bore I the shaft I've picked up the pressure back up another 12-15 Psi without having to go to thicker oil.

I was worried it was the MRL lifters ( since they have pressure fed rollers) but after talking to Mike I figured out where else to look.

Glad your back out there buddy !!
