Didnt read the entire post so maybe i missed something but 300 does seem low for a 327 with a blower. I think 327 with that cam and good heads should make 300 without the blower.

What type of dyno did you use. Was it a mustang dyno otherwise known as the heart breaker. They read much lower than most dynojet dynos.

Was the engine tuned for the blower to safe or performance levels. sounds like its got the safe tune running and needs some tuning to make some power.

Also do you have a lean rich guage hooked up. This is very important on a blown engine. Helps keep the tune in safe level and can alert you if the fuel pressure drop suddenly.
