Bylkins Brent are these valves 1 piece or welded? Am interested.
As far as sand box, it's was an old John deere mud tractor tire. The sand is all gone and flowers are growing.
As for the
oil pressure thing, I listen to the OLD masters from the 60's who ran these motors at 8,000 rpms and didnot break them. Sorry I'm old school and run every motor in my stable with HVHP
oil pumps and have
oil modes done for return and getting to the right spots. 15 years and still running the same HVHP melling pump with 100 psi spring and no wear on distributor or billet shaft. also have a small trick for this too. About .010" hole. Going to work, later. Rick
