With a 3L SC engine, stock with CIS pistons and webers you are going to see 200-210 hp. That’s with backdated SSI exchangers. From there to get to 250-270 hp is going to get expensive. You could boattail the crank, that’s good for 10 hp. After market P/C, that’s non Cis pistons and with appropriate jetting of the carbs and an MSD ignition with a suitable muffler. You could achieve 250-270 with existing sc cams.
Another way to get to 250-270 hp is weight reduction. Look that up searching the threads whereby 400 ibs have been removed from a 911.
