OK I have a 1976 Chevy C20 pickup with a 350 I just rebuilt the motor and now it won't idle on it's own and I have no power in 3rd gear can anyone help me

check for vacuum leak for the idle or idle mixture screws settings
no power in 3rd gear can be low fuel level, filter problems , ignition timing ( static is 12 degrees BTDC idle )
more than likely a vacuum hose missing after assembly

I have a 81 Chevy c/10 Scottsdale with 350 Pontiac motor it cranks hard but will start should I get a bigger battery and I know the starter is bad cause the solenoid pops out are these my problems

fix the starter solenoid problem or get a heavy duty starter motor for the engine They spin the engine easier and faster than standard units
Next for a V8 350 I would be using a 750 cca battery or the next biggest battery that fits the carrier
check the ignition timing and adjust to 12 degrees BTDC as more than that makes for hard starting

What should the timing be set at for a 1980 chevy 350

around 4-6 degrees before top dead center / BTDC to start,then you can set it for more if you need to smooth out the idle.On my 74 350 i didnt go more than 10-13.idle should be at around 700 rpm's.So if 4-6 makes it to low then advance it till it hits 700 rpm.

1989 Chevy K2500 350 will not restart after warmed up? I have replaced Heads, reset timing 0 TDC new plugs, coil, cap, button, module and pick up coil. Engine starts cold runs great but will not restart...

tdc is usually set at 8 degrees BTDC for an automatic and 4 BTDC for a manual transmission. This may help. Does the engine run rough at start up being set at 0TDC?
