What does the ratio on a roller rocker mean?
The rocker arm ratio (whether they be stock or roller rockers) has to do with the offset of the rocker fulcrum. The stock rocker ratio on the small block Chevy is 1.5:1. This is important because it effects your valve lift. For example, a camshaft with .300 lobe lift will yield a .450 valve lift with the stock 1.5 ratio rockers. Multiply the lobe lift times the rocker ratio to get your valve lift. Now, that same camshaft will yield .480 lift with a 1.6 ratio rocker arm and .510 lift with a 1.7 ratio rocker arm. More lift is good as long as your valve springs can handle the extra lift and you don't run into valve/piston interference problems. You are more likely to run into coil bind with the valve springs than an interference problem though. When in doubt, make sure to check just to make sure there will be no problems.
