    Cam gear shot the dimple between white out dots is from a snap punch,did nothing on the distributor gear. Got a MSD set coming. Someone told me there some soft gears out there and could they lowered the zinc content in motor oil, and I should add some?Can anyone give me some advice ? Please post it or call Walt 916-747-0051 thank you. That was my third gear in tho motors with low millage .

    We learned about fuel pressure and blow thru turbos on a friends Studebaker. With a mechanical pump, you get about 6-7 PSI, once the turbo pressure exceeds that, the pump cant push fuel into the bowls and the engine starves. Had to go to a variable pressure electric setup to get it to run right.

    Thank you Bob ,we are using a fuel pressure regulator that has vacuum line going to a vacuum source thats resets the fuel pressure the higher the boost the higher the fuel pressure.

    Walt, go with the bulltear matched gears, change both at the same time, DO NOT USE A NEW DIST GEAR ON A OLD CAM GEAR, or visa versa that will almost 100% result in a failure.

    use two new gears together for best results, even if the dist. gear looks good, if the cam gear is munched then the dist. gear is junk, guaranteed!

    We got it going with new MSD gears, have a oil pump mid plate and bypass plate on order from Bulltear , with the Zinc oil additive I hope that will take care of the gear problem. We are trying to get a stumble out of it around 2,500 rpm then it comes on nice and strong, we have went to larger jets,that helped some ,going to try larger squrters next. Any addvice out there ? please speek up thank you Walt. PS cant wait to go to a Mopower show later this month, they normaly have a good AMC show up.
