Default Rocker arms

After rebuilding my stock 350 I put in a 480/288 cam but used my stock rockers and have never really been able to get the full power from it and am wondering if I should have went with 1.6 ratio roller tips and if that would help performance. Thanks

No. Something else causing it.

dunno your compression but if ya stick a big cam on top of a low comp motor; it'll be sluggish everywhere but at top end.

So you what everyone to guess whether your lack of power is the 1.5 ratio rocker arms or the parts you put in your rebuilt engine or even if it's tuned correctly? My answer is all three circumstances are possible and I assume poorly done.

Agreed, so many possibilities. What pistons, what deck height. Chamber volume, squish band. Intake, exhaust???? Really?
yes I run 1.6-1 rockers. Yes I know all of the above. Yes my car is running hard. After MUCH tuning!
