I have an early Edelbrock F380 FE intake with the small carb flanges Also have 4 WW Stromberg carbs off of early Dodge truck poly 318 mills Any problems with 3 of the carbs working together ?? Progressively or all 3 three tied together Will be going on a . 040 over 390 or 418 ( .040 over 390 with 428 crank ) Ricky.
If you are going for "eye candy" only, then all three together. If you are going for performance, I think you are going to be very disappointed. If you compare apples to apples and do the CFM on a 4 barrel scale, these three are about 450 TOTAL; whereas a single 4-barrel on a 390 is about 625. With carbs that small, the internal venturi air velocity is going to be very high. Your 390 might display its displeasure by demanding a fill-up at every filling station you meet. Jon
