WHAT MAKES MORE POWER, CARBS OR EFI? WHY NOT RUN BOTH? CAN I RUN A DRAW-THROUGH CARBURETOR ON MY M90 BLOWER? CHEAP, JUNKYARD M90 CARB MODS MADE EASY! CAN I COMBINE CARBURETION AND EFI ON MY JUNKYARD-BOOSTED LS? CAN I TUNE THE CARB WITH EFI? DOES A DRAW-THROUGH CARBURETOR LOWER THE CHARGE TEMPS ON A BOOSTED APPLICATION? IS THE LITTLE M90 BIG ENOUGH FOR A 5.3L? CHECK OUT THIS VIDEO WHERE I RAN THE M90 ON THE CAMMED 5.3L WITH HOLLEY HP EFI, THEN ADDED A 650 HOLLEY CARB TO THE BACK OF THE BLOWER, THEN COMBINED THE TWO TO DIAL IN THE A/F MIXTURE.
