Re: Jeg's Hydraulic Lifters USA Made

I don't know where the lifters in question within this thread come from, so I won't speculate about that. What I will say is that I do know people in other industries who pull off calling their items "Made In America" specifically because of the Fed's guidelines around cost of goods sold, specifical...

Re: Jeg's Hydraulic Lifters USA Made

How much crown (convex) should be on a lifter to spin properly? We have a lifter crown gauge. It's been zero'd on a flatness surface (aka "surface plate"), then place it against the face of the lifter to measure the height of the radius at the center of the crown. The 0.875" diameter Johnson Hylift...

Re: flat tappet cam cores - what's the status in 2021?

I just watched one of my cam grinding colleagues fly in a machinery maintenance specialist for a full week who completely re-plumbed, re-valved, fully inspected & serviced one of his Berco cam grinders. That machine should be good for another twenty years, and according to his Cam Doctor was still p...

Re: Rocker arm to poly lock clearance

The unfortunate situation(s) you are observing with your valve train setup is compounded by several factors, including not just the rocker arm but also the cylinder head design itself. You may recall that the very first generation SBF Twisted Wedge heads were so geometrically out of whack in the are...

Thanks Paul Using the Miller Half lift theory, The same one Chris Struab advertises I apologize in advance for going on a tangent :) : just for clarification, the Straub video (to which I think you allude) does not show the Mid-Lift standard; that video demonstrates what is known as the Minimal Swe...

Working on some 23’ Brodix heads with Ferrea 2.100 valves .100 long. Currently set up at 1.900. I’m having trouble getting the half lift method of pushrod configuring to work out.

The general rule of thumb for rocker arm nut thread engagement is 1-1/2 times the stud diameter. Therefore on a 7/16-20 stud the poly lock should have at least 9 threads engaged at a minimum, not “3-4.”

Re: SBF Oil Pump Spring Spacer

SBF factory oil pressure is 40 - 60 lb @ 2000 rpm. I want to increase it by about 15 - 20 lb so, I'm assured to have at least 60 - 75 max lb. Is there a spring available to do that or do I need to add a spacer behind the stock spring? Are you saying you want "60-75 psi max" at your noted 2000 rpm? ...
