390 REVs
Every time i get the urge to really lay in to her i often wonder what my engine would like me to shift at. In other words what would be the max SAFE rpm for my engine? Its got MSD ignition/dist, Edelbrock 750, Hooker super comps, and the previous owner put a pretty hot cam in it (rough idle and the power really starts coming in at about 2500) and i'm not sure what the interanls have got but assuming there stock, minus a cam. So if any of you have ideas or personal experince of what these old monsters have got any info would be helpful. Thanks (P.S. i've had it to about 5100 myself)

Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
