timing help with a built motor

*sigh* frustration is setting in. ok 350 .06 over with vortec heads, dual plain intake edlebrock carb. voodoo cam 268/504. not sure if you needed that info but in case you did that's the build in a nutshell. i built the motor and painted the car and even did some of the machine work(work at a machine shop) and this was my first solo build so i'm dieing to get this thing right. my issue

i cant figure out how to tune this thing. when i time it where i think it need to be it runs for crap. my timing indicator is the stock one that has 3 triangular notches one of which is bigger then the others. i thought that was -0- when i turn the distributor and get the mark to move to toward the passenger side it runs better but then when i drive it down the road it wants to spit and sputter. if i turn the distributor till it sounds good and responds good to throttle it will scream down the road but i can still feel its off some... can someone just throw some things out there for me to think about and check? I'm kinda a newbie and have never tuned in a new motor.

thanks
brian

Cole is right. You need a timing light with an advance dial on it. Assuming your timing mark is right on, advance the timing until you have some where around 36-38 degrees total timing. Understand? You will be setting the mark to 0 with the degree dial set at 36. Not quite sure how to explain it better

you dont need the advance light if you buy a balancer cover that has all the degrees on it correct?

Get a Mr.Gasket timing tape. Or mark the balancer at 36deg BTDC which is 1/10th the way around the circumference .

Then mark it at 24deg BTDC which is 1/15th the circumference.

You want 24deg at idle base initial and 36deg at max centrifugal advance.

You need to modify the distributor to get this curve.

search my old posts on the subject.
