1963 C10 Bogging Under Heavy Throttle

[csermonet47]

Hey guys, new guy here. Picked up a 63 C10 a few weeks ago and have been trying to get it running right. I was hoping you guys could give me some new suggestions on stuff to check.

It has a 230 in it with a Rochester B.

What I have done:

-Rebuilt the carb (99.9% sure I got it right)
-Set the point gap and made sure the contacts were good
-New Plugs and wires
-New Distributor
-Drained out gas tank and confirmed it was clean in there
-Cleaned out fuel lines and replaced some of them
-New Fuel Pump
-New Fuel Filter
-Properly Timed

Here is the truck:



It runs fine when choked, but when the choke is off, mashing the pedal makes it bog and it loses power real bad for a second, then it gets back on its feet and revs up fine. When it bogs it will sometimes backfire or shut off. I messed with the air/fuel screw to see if it just wasn't getting enough fuel, but even backed all the way out it still bogs. While it is running better than when I got it, it still isn't right. Any suggestions on what to check next?

Thanks in advance,
Ryan
