I sent my Crane rockers to Crane to look at a problem with the front pins moving outward. They will replace the entire set for free (mine are Energizer series). They will upgrade the set to their Goldrrace series for $130.00. The engine is a BBC 468 , 990 heads, tunnel with 2 750's, 10.5 to 1 comp.,hydr. comp cam, Sanger pickle, used mainly for fun (skiing etc) with some high speed runs up to ~ 6000 rpm. I probably will upgrade to a solid cam (lost valve head this summer maybe due to valve float). Last owner ran a Isky solid cam model Z-55 (590 lift 300 duration, said engine was getting top of ~6500 rmp).
Should I go with the rocker upgrade (or just get free ones). Any comments on the Isky Z-55 cam or maybe a better one ?
Thanks
