| RE: Stock 390 = CJ carb? |

Terry, I've done this and can tell you from personal experience that it is detrimental on a stock 390 to go any higher than the factory-sized 600 CFM carb. There was no gain in upper rpm power and the car was slower overall. Performance, economy, and driveability all suffered with the larger carb.
It doesn't matter what carb you use...Carter, Holley, Edelbrock. They all perform exactly the same as far as the end result...mixing air and fuel. The Edelbrock and Carter require a little more tuning knowledge since you're not just chaning jets and power valves as in a Holley, but they're not difficult to tune at all. |
