Hey all!! I have some valve springs that I need help identifying. I got these years ago on a set of ported 289 heads, so I know pretty much nothing of what brand or where they come from. I have been doing some searching and found the Comp Cams 972's to be close, but the specs don't jive everywhere. Here is what I have measured on them:
Main spring:
1.455 OD
1.075 ID
Coil width= .191
2.065 free height
Damper spring:
1.100 OD (free)
1.010 ID (free)
.045 coil width
.250 coil height
.975 ID (assembled)
I have a set of GT40 heads on their way and figure I will need to change the springs, hoping these would do the job with the stock HO cam. If not, I will have to look into the Trick Flow set or something else comparatively. Thanks in advance for the help!!!
