Edelbrock Air Gap on Magnum 318 Problems

Like mentioned before, I doubt the intake has anything to do with the stumble, If it did, then throwing on the single plane would only increase the issue. It sure sounds like a carb issue. Do you know anyone with a good working carb that you could throw on? That HP 650 that you have there is pretty beefy for a 318 (depending on internals). Do you know how much horsepower and torque you are putting out?

i think 67 cuda has a good point. over carbing a motor can have anyone scratching their head, even though he didn't say that. swap it out to a smaller one and see what happens. sounds to me like you have too much fuel . fuel \air mixture is the secret to performance. a smaller carb may be the ticket. try it you have nothing to lose ,wont take long and then you can go to plan b if that doesn't help. good luck.
