Well im going from an out of the box 850 demon... so im hoping for a good decrease in my E.T.'S this 850 mighty demon annular on this new 388 sbc motor has been a tuning nightmare chasing jet, always fuel behind new power valves, and not very responsive and i hope this Pro systems Carb can get me closer... im 2-3 tenths off of where i should be.

thanks
Keith
