Thread: rollers or modified.

so no price's or place's to get L76 springs lol!

It's a GM spring, that's cheap and readily available at dealerships from what I've heard on the street.

Another low cost choice is looking to ebay for LS6 springs. Usually there is a set or two going very cheap. Only thing there is you shouldn't use them on a 96 or 97 head because of the shape.

• Coil bind height is 1.125".

And some L76 info, quoted from RegalGS and other sites.

The L76/L92 valve spring. Part # 12589774. With a GM list price of $3.59 each. (Pace Perf, $2.59)They have the same 90# seat pressure as the yellow LS6 spring, but a lower spring rate. LS6 are 375#/in. L92 are 348#/in. The Comp Cams 105# springs have a spring rate of 313#/in.
These springs actually cost less than our stock springs.

The valve spring specs for the GM springs are on page 281 of the 2008 GM Performance Parts Catalog. The L92 spring does have a limit of .530 lift so it is for rockers and mild cams, like the VS. By my calculations, at .500" lift the L92 and the 105# Comp cams are within 3 or 4 lbs in total pressure. This is a lower cost set up that should lower the wear compared to the LS6.

From the GMPP catalog 12589774
Valve Springs
• Beehive style springs
• Standard L76/L92 springs
• 1.800" installed height @ 90# pressure
• 1.300" @ 264# pressure
• Max lift .530"

Oops sry man . I just decided to re-visit this thread. I think i paid $80 for mine, i got them from the dealer. If i were to do it again, i would buy from Pace, there prices are pretty good.

FWIW, I just found my receipt for my L76 springs. About $32 from ZSPOT on NAIOA.com. So, 05SS45, if you're looking for springs, I'd contact ZSPOT no matter what spring you go with.

o sweet whitelightnin thanx dude!

Do I have to pull the motor on an 05 to install a cam. Thats the only reason I would use rockers instead.
