Camshaft RPM range

I currently just have my rev limiter set at 4000 rpm, probably a few lower than peak with the 204/214 Edelbrock Performer plus camshaft. Curious where you guys would set the rev limiter with a hydraulic roller 218/218 .541/.541 with 1.65 ratio rocker arms with a 112 LSA? I was thinking 5000 rpm. Thoughts?

SBO 350? You'll want to go higher than that. I'd think it would make power to 5200 or so with those numbers, so maybe 5500?

Yes, should be just under 9.5 to 1 Olds 358 with the new 68cc Edelbrock heads. Easy to change the rev limiter, SEFI with the Holley Terminator X Max. I was kind of thinking 5500 rpm Max but low 5000's being more realistic being a mild cam.

Just look at your VE table. You’ll see it drop off more quickly once you’re past the hp peak.
