Stroker 340>416 Build Advice

My take is if you are spending close to 2k on edelbrocks than try to get trickflows, a far superior head out of the box and not just flow numbers but overall quality. You cannot use stock rockers on them due the the stands being moved from the stock location to improve the rocker location/geometry but you can get the mancini roller rockers (made by harlan sharp but very reasonably priced) and they are almost perfect geometry out of the box. Rpm air gap, solid flat tappet cam, around 10.1 compression and you should make 450 falling off a log and more depending on the cam size and your tuning skills.
