No power!

[cheezsnake]

The engine bogging down when you first hit the gas can be pretty common in street cars, especially with vacuum secondaries. I had a 351C with an Edelbrock 750 that did the same thing. If I accelerated steadily there was no problem. But, if I hit the pedal all the way to the floor the car would bog down a little before it took off. That short initial bog you get, though, should be followed by a surge in power as the RPMs climb. You can correct some of this by advancing the timing a little. But, there may be some other problem with the carb that's causing it to dump too much fuel. If your engine doesn't recover quickly from that initial bog than something else is wrong, either with the carb or the ignition system.
