L6 250 Bogs When Starting from Stop

My saga continues. I just finished installing a new air cleaner and power brake booster. The brakes seem to be working fine, but after I installed all this stuff the performance of the truck took a hit. Before I started working on it the engine was as smooth as could be - very easy to start and very smooth acceleration from stop to highway speed. Now when I step on the gas it bogs and I have to rev it way up to get it to keep from stalling when I start from a stop. I put in a new fuel filter a month ago. The air filter is new. All the vacuum lines are new. New points, condenser, rotor, cap, and plug wires.

What should I look at first?

1979 Honda GL 1000 - retro touring at its best.

Past:
'05 Sierra 4x4 - Had 270,000 KM and running well when it was written-off by a stop sign runner.
'94 F-150 from the "F word" company. I'll admit it...good truck. Sold what was left of it for $800 to a guy who came to pick it up at 11:00 PM with cash in hand. Hmm.
'79 Sierra Grande (Black) organ donor - perfect rebuildable 4-bolt 350 and a good TH350.
'76 Sierra Grande (Orange) - hate isn't too strong a word. Kid who bought it turned it into a hot rod.
'68 C-10 R.I.P. - Dad's old truck...too far gone to resurrect.
'59 C-50 - with hoist. Truck is gone, wife isn't. Nuff said.
