Hi Charlie,
we have emailed in the past about a 715 CI that i am in the process of building.
Any how, I am trying to find some valve springs for my application.
C 460 head 2.20 installed height, 1.645 od.
Cam is 918 lift and next year i want to install a 950 or more lift.
I found a broken sping and am wondering if 1 broke, how long till the rest break? Don't want to slap a valve or worse drop 1.
The closed pressure is currently 340 and 980 open, these are the results that i got from testing them.
This engine will see a max of 6800 at the other end and shifted at 6000-6400. I am wanting use the softest spring for valve train reliability but realize i need a fairly heavy spring to keep the valves closed with that much lift.
Anyhow, can i get your thoughts and a price if you have something in mind for a good spring.
Thanks
alan
