Quote from: MiniDave on February 20, 2017, 07:52:41 AMIncidentally, one of Kent Prather's (engine builder) top tips had to do with oil.....he says the race oils like Valvoline VR1 and even Brad Penn that I use don't contain any detergents like modern oils do, and for this reason are not the best thing to use in vintage engines, although they do have the zinc needed to keep the cam lubricated. What he does is buy a special 100% zinc additive, and runs the cheapest OReilys 20W50 on the shelf, then simply adds the appropriate amount of the zinc/phosphorous additive. He also said you need about 1500ppm of zinc, and that VR1 only has 1250 - which is borderline. The Brad Penn has 1500ppm, fwiw.

Quote from: gr8kornholio on September 17, 2018, 12:06:56 PMMaybe I should have splurged for the authentic calipers instead of the mini spares copies. Anyone else make a 7.5" caliper?Answered my own question. KAD makes one that will fit the 7.5" disc. Pricey, unless this happens.
