Hi guys I have a 2003 vy ss With 302000 on the clock I just did an ls7 lifter upgrade comp cam 219/233 and crow cam duel valve springs and otr
xforce headers with hi flow cats and 2 and 1/2 cat back
4.11 dif gears with tru Trac
It only made 237 kw
on the dyno a lifter let go and I know have low oil pressure (reason was I had wrong valve springs in it for first run) all changed now.
I don’t know if it’s time to rebuild or do a set of lifters again and heads and bolts. I have already spent decent coin (plus we are building a house) what’s every one’s thoughts.
Cheers in advance.
