Default Setting up 977 springs....

Has anyone setup these springs on an LS1? I know Jay @ absolute has set these up. Looking on which retainer, seat, and keeper were used.

Default Re: Setting up 977 springs....

Ok.....I'll answer my own question....
To setup 977's for large XER cams you need the following....

Option 1)
.070 longer valves

Option 2)
Patriot Performance custom retainers
and hardened shim(.010 - .040)

Option 3)
Manley 5/16" beadlock keepers
and hardened shim(.010 - .040)

So far these are the only setups that will yeild the right install height(1.850).
