1966 mustang 289 sputtering and poping

Hi I have a 1966 mustang and it starts and idles fine but when I let the clutch out and try to move it sputters and bogs even when warmed up so I have to give it lots of throttle. I have read manny fourms and threads and can figure this out it seems like a fuel probably. But when I am cruising at 45 and give it throttle it sputters and I have to lightly give it throttle or else it pops and will stutter pretty bad.

I have a stock 289 but it has a edlbrock 289 rpm intake and a old holley 600 carborator. Also a crane cams points to electronic ignition box and a motor craft distibutor but a stock coil.

I will check the cap and rotor today and wires the plugs are new they are autolite 45 I gapped them 2 off of spec by accident could this be the problem? I also am suspecting it is the coil I put on a msd blaster coil and it burned right up can someone please help me. Any advice would be greatly appreciated. Jason

Why did the coil burn up? You should check your ignition system completely.
Start from scratch. Stock points and coil. Make sure your timing is set correctly 10-14 degrees at idle 800-1000 rpm. If that takes care of the sputtering you have a baseline. Gap your plugs also. Eliminate one thing at a time.
