Can the Crane iron rockers handle 6500-7200rpm blasts with a solid flat with 140/350 spring pressures & .515 lift? Or should I just go with Harland Sharp to be safe? I love my Sharpe's on my 440, 6500rpm everytime it gets started & after a year the lash is still dead on. The new rockers will be on a 11:1 iron headed, tunnelramed 383.
Thanks.
