weights of valvetrain parts Does someone have a list of different valvetrain components and their weights? I need valves, springs, retainers, rockers, etc.
I don't care if they're stock or aftermarket, but the more the better, of course
All i found so far is the weight of LS6 valves and that Harland Sharp rockers are 10.6 grams lighter than stock rockers.
I know someone has to havevalvetrain parts sitting around before install, could you weight them please? Thanks!

How is this for a valvetrain weight spreadsheet?

Wow, that is some awesome data! Thank you so much, Brian@TEA.
You wouldn't also happen to have weights for rocker arms(without fulcrum), lifters, and pushrods, would you? How about spring rates, rocker arm stiffness, and lifter stiffness?
Once again, thanks for all the great info, I'd never guess that Z06 stuff is so good.

Seems like a very friendly company, and they were more than willing to answer my questions.In a nutshell, off the shelf valves are around $100 each.

Just some insight into the weight arena. I grew up in a show and was taught the old school guys were really "dumb" for running 3/8" pushrods on their SBC back in the 60's and 70's. All that weight with the oil was not good. Well with Spintrons, optical scopes, we are now able to see what goes on. Well the old timers were right. Big pushrods are the way to go. Wether it be flat tappet lifters at 9500 rpm for 500 miles or mech roller stuff at 8000 rpm for 1/4 mile, large diameter pushrods make more power. Why? Stability. We now have learned pushrod deflection is a killer and what we thought we would gain with lighter parts actually was robbing horse power. It is common now for a performanc engine to have 3/8", 7/16" and even 1/2" pushrods in small CID configurations.
For every action their is a re-action. It's a thin line to balance.
