Need Help?? Want To Build A Streetable 327. Need Advice??

I JUST BOUGHT A USED 327. FROM WHAT THE MAN TOLD ME THAT I BOUGHT IT FROM, IT WAS FROM A 66 EL CAMINO. HE SAID IT WAS THE 300 HP 327. IT HAS BEEN REBUILT. STAMPS ON THE PISTONS SAY IT IS BORED 30 OVER AND HAS 461 CAMEL HUMP HEADS. THE MOTOR HAS LOW MILES I CAN STILL SEE THE HONING SCRATCHES IN THE CYLINDER. I TOOK ONE OF THE ROD BEARINGS OFF AND JUST HAD A LITTLE HAZY SCRATCH BUT LOOKED GOOD. IT DIDNT LOOK BURNT OR DISCOLORED.

SO MY MAIN QUESTION IS I NEED SOME REAL INPUT. I BOUGHT A EDELBROCK EPS INTAKE MANIFOLD DUAL PLANE, 650 EDELBROCK ELECTRIC CHOKE CARB. I WANT TO REPLACE THE CAM WHAT CAM SHOULD I GO WITH? I SAW A CAM WITH LIFTERS ON EBAY FOR 150 AND THE SPECS WERE FOR THE 350 HORSE 327?? I JUST PLAN ON CHANGING THE ROD BEARINGS AND MAIN BEARINGS AND LEAVING THE PISTONS AND RODS IN PLACE. ALSO DO YOU GUYS THINK I CAN RUN THIS MOTOR ON PUMP 92 OCTANE GAS? WITH THE 350 HORSE CAM?? I WOULD LOVE TO GET MOST OUT OF THE MOTOR WITH OUT HAVING TO CHANGE THE HEADS. SOME ONE TOLD ME ABOUT DISHED PISTIONS AND KEEPING THE HEADS. HEY GUYS LET ME KNOW WHAT WOULD YOU DO WITH OUT CHANGING TOO MUCH STUFF AROUND.

I WILL BE PUTTING THIS MOTOR INTO 65 SS IMPALA. ITS A FULLSIZE RIDE AND IS PRETTY HEAVY. I HAVE TURBO 350 IN IT NOW WITH A 283 WITH POWERPAK HEADS AND DOESNT PING AT ALL. I NEED SOME GET UP AND GO. ITS HARD FOR ME TO BREAK TRACTION IN THE 283. SO PLEASE HELP ME GET THE MOST OUT OF THIS 327. WITHOUT HAVING TO CHANGE THE HEADS OR THE PISTIONS AND HAVING TO RUN ON RACE GAS. I NEED A GOOD STREET READY MACHINE. YOUR INPUT IS DEEPLY CONSIDERED
