I RUN A STOCK 350 IN PURESTOCK CLASS. OUR CAM RULE IS STOCK 260 LIFT. I WAS TOLD THAT I SHOULD RUN 1.6 ROCKERS INSTEAD OF 1.5. THEN A GUY TOLD ME THAT I COULD RUN 1.8 ROCKERS OFF A BIG BLOCK. IS THIS POSSIBLE AND WOULD I HAVE TO CHANGE MY RODS.

THANKS

I've never heard of puting big block rockers on a small block, You had better do some research on that before you try It. The 1.6 will be just fine for that application. Just my 2 cents.

Putting big block rockers on a small block is an old Smokey Yunick trick dating from the early 70's. It is not a job for a slam bam shop, or the faint of heart. This is big buck stuff. The rocker stud holes are plugged, and the centerline is moved away from the valve .150". Pushrod to head clearance must then be reestablished by a lot of grinding or machining. Valve covers must be severely massaged to clear pushrods and rockers, so everyone will know what you're doing. If you use stock BBC rockers, the ratio is 1.7. If you want to pursue it, there is a step by step in H.P. Books "How to Hotrod Small-block Chevys", 1976.

Crower has cured the machine work problem . He sells high ratio rocker's now , that have a big block body with an offset trunion . They will bolt right up to standard 7/16 stud's in stock location . We use them a lot on street stock applications when we use a 1.8/1.7 combo , or the 1.7/1.6 combo .
