408 Stroker Build Suggestions

Going with adjustable rockers helps in a few ways. I wouldn’t limit my lift because I have new stamped steel OEM style rockers. Even more so with heads that flow well beyond a low .500 lift.

Your best bet is to take advantage of the heads air flowing capability and use a stronger true ratio rocker arm with a cam that has enough lift to get into the heads power making abilities.

The stamped rockers are not a true 1.5 ratio but a good rocker is! There are 1.6 ratios available for the LA engine.
