Nothing like a blower. Gonna run carburated or injected?. Back in the day we ran a v-671 Dyers blower on a 302 in a 69 fastback mustang. When it was on the track we ran 12-18psi of boost. On the street however we would drop it down to about 8psi max. You couldnt hook it up even then on the street. We ran 2 4412 Holley 2 bbls. They had some work done to them to flow a little more but the biggest problem we had was keeping it from loading up sitting a stop light. The problem with a blower is the massive vaccum on top of the blower and boost underneath keeps the power valves from opening up to richen the motor at higher rpms. If you richen up the mixture then it wants to load up all the time. The ol man tapped in below the blower and brought a line up to supply positive pressure to the powervalve chamber to open them once you were off the idle circuits. Sounds confusing I know...lol. If you need help let me know.
