Lifters
Just wondering why lifter types were not included like solid, hydraulic, solid/hydraulic roller, and direct acting mechanical buckets? I know the valvetrain tab is already pretty full but, if different conrod and piston types were included....solid would increase loudness and reliability, hydraulic would reduce loudness and reduce reliability a little bit because of more components= more chance for breakage, etc. But then again why not also include pushrods and valve types and seat angles, unnecessary complication i know.
