GM847...springs.. Well opti went south and timing cover was leaking...TIME FOR A CAM!!
I planned on using the Cran CRN-10308-1 Spring and retainer kit. But I was wondering if I need to worry about coil bind and does anyone have any meaurements of what I am talking about. Here are the specs on the springs...
Outer Diameter 1.460
Inner Diameter 1 1.075
Inner Diameter 2 0.803
Damper NO
Seat Pressure @ Installed Height 130 lbs @ 1.850
Open Pressure and Height 402 lbs @ 1.150
Coil Bind 1.080
Maximum Net Lift w/.060" Clearance 0.710
Average Spring Rate 391 lbs/in
Will these springs be good enough? I just dont want to run into coil bind and break anything. If you have a GM847 on stock heads, what springs did you run and did you use shims?

Ok, this is pissing me off. I post something that the search WILL NOT bring up and get ZERO technical help, but the stupid posts get LOADED with crap. Where have all the people with technical knowledge gone?
