Need help asap 340

im running comp ultra pro magnum roller rockers on my 360 with a good sized solid roller so they handle the extra spring pressures. If the engine was just rebuilt before I wouldn't touch the bottom end, but I would figure out why the problems occurred. Other than that I'd change out the cam and top end like you said. You could do a supercharger but that's dependent on if the bottom end could take it. So ring gaps correct and so on.
