The spec from Hughes for bottom protrusion underside the rockers is .450" which equals about 2-3 threads sticking out of the adjuster screw give or take a little

Yes, I am talking about the OD of the cup, that is all...at max lift the clearance spec is as I mentioned in my original post. So I am just wondering, based on the fact that im not sure what gauge my checking pushrod is (made it out of a junk one my dad found at work last year) if the 3/8" pushrod cup will hit since I only had 5/16" pushrods last year




The cup OD will be the same size so you dont have
to worry about that if you have clearance now
