truck ain't actin right.. help please

I have a 75 ford f100 4x4. Turned the 360 into a 390. 750 holley, performer intake, stock heads, performer plus cam, sanderson headers. At first the truck ran great everything I wanted. Just so you know the truck gets driven mabe once every two weeks or so mabe just to take down the road or hit the trails for a little bit. About a month ago I noticed it was idling very high and sounded like crap, and was loosing power in higher gear,and I could not figure out what it was. I thought mabe the carb needed adjusted or timing was off. Turns out the plug I had on the vaccum block on the back of the intake where the brake booster runs to had came off causing a bad vaccum leak. I have plugged it up again and sounds way better but now in each gear starting off it just does or just does nothing if I get on it. While idling if I get on it it revs up but starting in 2nd and getting on it, it dies or just ain't got no power till I let off the pedal and ease back on it again. Please help. Did I mess my motor up? Did I knock the timing up to high/low. I didn't even mess with the carb. Any help would be appreciated.

I would start with timing. Have you replaced the timing set? Dizzy? Damper?

The dizzy is stock the rest aint. I just went and knock the timing up a little bit and took it down the road and it was fart knockin so I "tapped" the timing down a little and turned around and got on it and it got sideways in the road so I reckon that was it I had knocked the timing down low when it had the vaccum leak.
