GM Valve Springs

[87Turbo-TWE4]

Does anybody have the part number for the stockers? I can't find them on GM parts direct.

 

[87Turbo-TWE4]

Anybody? Maybe a suitable aftermarket replacement?

Some people swear by them, others will tell you to stay away from them. I think they are fine for mild builds that dont need a whole lot of RPM's.

I have a brand new set, still in the box I will sell you for $40 shipped. :wink:

VS739R are the 100# LT-1 spring.
VS-744 or 677 is the stock replacement

 

[RegalT-type85]

might as well got comp/LT1 springs.
