I ran my 79 SC 3.0 at 8lbs with a 6BTM MSD boost retard ignition system and a 7th injector that fired off a Hobbs pressure switch at 4lbs without an intercooler and SC fuel dizzy. 8.51 compression, I had no problems. The pistons are the weak link, I wouldnt go over 8lbs, and with the higher compression you will still be laying down some good horsepower.
I rebuilt using full fin 3.3 pistons and cylinders with the rod bushing modification, twin plugged it, 930 oil pump, and added a 86 930 Euro fuel dizzy an intercooler and still have a 7th injector hooked up to an adjustable pressure switch just incase i need it at 14lbs..
