Reply to "Rocker arm lift ratio"

Don't try. The stock 351C ratio is 1.73:1; big-block Chevys are 1.70:1. The highest ratio rockers around are 1.80, used for NASCAR racing and more expensive than the replacement cam you want. When you do get the new cam, be sure to include new lifters or very shortly, you'll need a second new cam.... and still will need new lifters.
