Jamo -
As I recall you were using straight 50 weight
oil in your motor - I don't think that helped your distributor gear longevity at all especially since you were probably using a high volume
oil pump on top of it...
I f I were you I would go for the hydraulic rollers.
The clamps I referred to are the ones that Turk and I used on our ERA's...different from the ones we saw at Shelby.
Jack -
I am also using the Crower roller lifters based on improved oiling - a good choice I think.
