I have a classic 65 F100 with a 72 Gran Torino 302. I am kind of stuck on an issues here. While at cruising speed at random times, (more after cold start) I loose throttle. The engine bogs down. I can pump the gas/pedal to floor, but nothing happens. Ill pull to the side of the road and stop, then the engine picks back up again and runs fine. I just recently replaced carb 1404 with a new Edelbrock 1405, added fuel pressure regulator set at 4psi, newer performer 289 intake, added 1" 4 hole carb spacer,  new fuel lines, new distributor (flamethrower ignitor 2), (has older master blaster 2 ignition coil), new plugs, new wires, new fuel tank, new Delphi mechanical fuel pump, new battery. Installed new negative lead on battery and new ground lead to frame. I also just rebuilt top end due to bad head gasket. Adjusted timing to 8 for initial, haven't set total yet. There is some sort of new noise, a howling sound (not whistle) (vacuum leak somewhere, not sure?), on drivers side of engine. I am having trouble pinpointing sound. My fuel economy is terrible  as well. In 30 miles, I burn through a 1/4 tank. Engine starts just fine, idles great and runs good, except for the bogging down and fuel economy.

Welcome!  Did it run fine before the carb and intake swap?  It might be a vacuum leak.  Check all your hoses and spray carb cleaner or use propane to check especially around the intake and carb since you just swapped them.  Start there and report back.

Thank you for the reply. I bought carb cleaner to do testing yesterday and plan on checking today.

also, replace the fuel filter.  Fuel pressure should be higher (6.5 max)
