Title: Better valve spring
Post by: grand camino on April 02 2011, 11:21:06 AM

I'm looking for options other than a comp 980. I posted at the buick site and most are ok with comps.  I read where comps can be, and are, inconsistant.  My 204/214 is 4 years old and quiet. i have always run good oil and ZDDP. I was thinking 100/105 seat pressure would be ok. I like the idea of a GM part, like an LT1 spring ,but now i hear they can sell knock-offs as well.  any suggestions appreciated.

What are you shifting the car at and what rpms do you cross the traps at? How many miles on the springs?

I'd like to see 5200 but it seems to go flat by 5000. The spring are 4years old.   I'm seeing  high 10's/low 11's on my wideband  during a blast and car runs great. zddp always as well.  Not a drag car...but i do beat up on my friends lightning and mustang now and then.  Kirbans springs seem like a decent choice, yes?

Personally, I would stick with the 980s which should turn that cam easily past 5200.  I would rather do that than suddenly increase the pressure upward and take a chance on increasing the wear on a cam that has been in the car awhile and settled in...but that is just me
