? For the Forum on Adjustable Pushrods

Here's a quick article on valve train geometry which in essence is what it sounds like you're working towards. I personally am not familiar with using adjustable push rods across the board in a running engine.

Very good article. I learned some things. When I built my 273 I had milled the heads, a thicker head gasket, different cam, and although still solids, different lifters. What a mess. Tolerance stacking is what it's called. A few + thou. there, a few - thou. there. Things just didn't line up. I got different pushrods and shimmed the rocker shafts. That looks better. I didn't check it with a marker though. Learn something every day. tmm
