Right now I'm building a predator 212cc and the engine is a Hemi. Aside from the necessary flywheel, carb, exhaust mods...
It will have the original head, 1.2 ratio roller rockers, original valves, 26 lb springs, a lift for the valve cover, a mod 2 Dyno cam, and a flat top piston.
My issue is that I have no idea what the push rod length needs to be. I've read in the forum about using playdoe or clay to check for clearance, but I don't even know where to start with the rod length.
Secondary question: Does the valve lash stay the same with the mods I'm doing, or will it change.
Any help is much appreciated, and I'm open to any suggestions or improvements.
Thank you
