Would like everyone recommendation for a rocker arm for a 427 with a hydraulic flat tappet cam in the 520 lift range. I can't remember spring pressure nothing dramatic. I just want reliable and wondered if GM Performance long slots would be sufficient or should I use a roller tip rocker? I really don't thing I need Comp Pro Magnums like I had on 496 solid roller motor that was mostly a strip toy. Thanks

GM Performance long slots are all you need IMHO and experience.
Thats what I have been using with a cam that has .550 lift

Long slot Comp Cam stamped steel rockers, due to their accurate *actual* ratio. :thumbsup:

Aftermarket is sooooo much better. Actually, the car was still working fine when I took it off the road in the fall of '77 so it could have gone more miles still. We were building a house, raising kids and just didn't have the time for the car. It will be out again some day.
