G-10, Thanks. I agree with the aticle on the Mid-Lift site. Great stuff. When I started my design I thought I was alone. About a year later I saw 2 others had done the same thing because of the lack of any manufacturer doing them. Joe Fontana had done it back in the 80's and Don Ferguson was doing a set at the same time as me. Don's and mine were very close. I wish I had thought of stepping down the adjusting nut to make the push rod shorter. I used 2 torrington bearings side by side with a gap for oil which he didn't. Joe made his own adjusters from set screws, something I would never thought of. Hey necessity is the mother of invention.
When people see the Clifford 292 manifold on the side of my 302 GMC, some still can't figure out how I made the round ports in the manifold.This is what using an old style engine is all about...Good Luck...J.D.
