OK see one idea of 170lb/400lb Open..
Looks reasonable..ANY other feedback...?

What is the breaking point?
I am on the NO Roller Lifter side of the argument and No Roller Rockers.
Will Stock Stamped Rockers should survive this rating?
Already saving money !

Should we also Limit Retainer Height to say 1.80 inches?

Are many cams exceeding 550 inches lift?
Most seem to be in the .400 to 450 inch range..

IHRA and NHRA has to be watching this !
