350 engine with 650 Holley DP, 4 speed and points.
Car starts ok and engine revs good at a stop.
First noticed problem when I let up on the gas, car starts bucking,
mostly in 4th gear.
Now it appears that the bucking is in all gears even under excelleration.
I hit the pedal hard today in first gear to see what would happen.
When the secondaires kicked in the car bogged down and ran like a semi.
I need some help on where to start looking for this one.
Electrical or mech?
Could this be my fuel pump?

I have seen cars act like this when the points are bad. (Engine revs easily in neutral but has no power). Check your dwell and the condition of your points.
