Cam and a tune might be all you want, you'll need a diablo hand held tuner, then hook up with a good tuner and do it over e-mail. I know with a stock 392 they could get another 30-50hp just from a good tune. There are many that offer the service but www.ostdyno.com is the best I've heard
Thank you. I'm guessing that this would necessitate 92 or 93 octane to run? Here in CA, 91 is the best we get aside from race gas. I don't want to run $5.00 per gallon gas all the time!
