6 Pack Issues

It's probably been mentioned already but 6psi is recommended for the SB 6 pack. 195 thermostat also recommended with the setup. The exhaust crossover left open is also suggested . That said I'm running a 180 thermostat with out issues YMMV. Check to make sure the throttle plates are not sticking on the front and rear carbs. Early carbs had that issue.
