289 Hi-Po Specs?

Does anyone have any info on the Specs of the 289 V8 Hi-Po engine from the 60's? I friend of mine has a 289 which isn't the Hi-Po version and I wanted to know the differences between the two engines for when I rebuild this one. I'd like to make the changes to get the extra horsepower out of it without going into some major engine modding.

About the only Difference was a HI-PO mechanical camshaft and screw in rocker studs. Shelby added an aluminumdual plane intake, TRI-Y headers, HOLLEY center float 750 CFMand balanced the whole thing. I believe this raised it from 271 to 306 HP.
