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

You really need the OEM shop manual - good luck finding one, but if you have the engine code, you may get help Googling it. Pros always mark each item they remove so that they know where it goes on reassembly.

I went google and typed in-- 350 chev engine suffix number ce 4329 and found a page chev-camero.com>chevy-camaro
listed is a ceu--1980--350--190 hp
these 4 bolt main blocks were sold here as bedford truck engines ( 5 ton trucks) as they had a slightly longer stroke which gave a better torque rating for heavy loads
They were popular as street engines, because they gave better power bands that could only be got by regrinding the crank to gain more cubic inches( longer stroke ) a 350 engine and adding special head gaskets for the piston protrusion above the block
Along with good cams , the 4 bolt main negated the need for expensive main modification to handle the extra power
anyway go to that site and navigate around and you may find the information you want

The block can be either 2 or 4 bolt main.
You have to look at suffix letter in front of the block on the pass. side. Behind the alt. There two or three letters. That will tell you the history of the motor.

any parts store can print you out a diagram

You only need one ignition hot for this. Look on the coil cover and it will say BAT and TACH above the plugin. Hook to BAT. Make sure your vacuum is hooked to a constant vacuum (manifold runner is best).

Timing mark's on cam and crank should meet, if you did not put distributor out, just set timing gear's as shown, it you did pull it out, stab distributor 180 off, hope this was very helpful.

1-8-4-3-6-5-7-2

On that set up the computer mainly sets your timing. It reads the timing off of the crank sensor, cam sensor, it tells the injectors and coil packs what to do.
