What camshaft lift, spring pressure open/closed, rpm, preload, valves/valveweight were you using?

 

are you talking about an aftermarket ls7 rocker, or the GM rockers sent to HS to have them replace the trunion/bearings?

either way....my guess is, nobody.

i had the gm rockers done by them, and they were stout and have no problems.

 

You might get more responses on LS7 rockers in the Gen IV Internal Engine Forum.

 

aftermarket HS rocker bodies. Greg what lift ont he cam you were runnign?

 

if i recall, i believe .669 intake and 644ish exhaust. pretty aggressive. it was a cam motion grind.

fwiw i had 2 stockers fail. the HS mod fixed that.
