Good Cam for 69 340

I would'nt use the stock stamped rockers even mild performance street engines. The ratio's are less than poor. listed as a 1.5 but are really 1.41 to 1.45 leaving a lot of lift (power) on the table. a Few years ago I tested many sets and best one was 1.45 worst was 1.41 most were in the middle somewhere. Combined with the fact that the lifter is not in plane with the pushrod on small Mopars really compromises the lift in these engines. However the stock '273' adjustable rockers are a much better choice, but aftermarket is best. 1.6 ratios will give back most of the lost lift from lifter/pushrod angles . Do the math using 1.43 and you will see JMHO .
