65 K10 has no acceleration power/ throttle response

[1970conroy]

Recently picked up a 65 k10 step side. PO gave up working on it and got it for a good deal. First i got the correct b&m shifter linkage because he made some linkage but it was wayyyyyyy off from what it was supposed to be. Anyway got it to engage properly and took it for a drive. The truck has absolutely no power or throttle response, it will stop and go but doesnt seem to shift nor want to accelerate. Set timing @8 BTDC,new plugs, checked vacuum line/ vacuum(around 10) and just cant figure out whats wrong. Could it be the governor, modulator, blown rear end, bad tune in carb? Its got a mostly stock 350 with edelbrock 1406 carb and intake, with a th350 and 205 transfer case, will post some pics soon
Any help would be greatly appreciated
Thanks guys
