Any good books about valve train geometry?
 

Trying to figure out pushrod legnths and im finding that this is something that i dont fully understand and i need to learn more about, are there any good books out there or other resources about setting up proper big block valve train geometry?

you might want to try Dennis Moore's book "Big Block Chevy Marine Performance". really explains the marine big blocks. Got mine a few years back by calling Moore's performance @ (626) 675 3548. Great book.

Do a search on here about Mid-Lift. Jim Miller has great information about this.

This is the Article from Jim Miller and the mid-left theory Rocker Geometry
