Not many people have gone over the .550 lift and not broken springs within a few thousand miles.Period!If your stuck on running that high a lift which even on the exhaust isnt going to net much HP adv. Get the comp cams new Mod Springs or wait for SHM to put out his Double Springs that I personally know is going to come out in a month or two:o they can handle the lift but for how long ??????????????
COMP CAMS
SHM
ERSON
CRANE
CROWER AND A COUPLE OTHERS I CANT THINK OF HAVE LIMITED
THIER LIFT TO .550!!!!
There is a reason for it none can safely go that high with the Mod Valvetrain Yet.Now when you get that many Man. that limit the lift there is a reason thats all Im saying.Its your motor but after all the money you are puttin in to it if a spring breaks and a valve goes down :o
Now is that worth the little extra lift???You make the call!!!
