350 4bolt timing help+Carbholley

[12milesagallon]

Hello everyone, I am new and glad Ifinally found a site that can help me! I have an 86 chev3504bolt main, Zero decked, with a timing problem. My friend built the engine for me and he said the damper is the right damper but the timing mark points toward the #1 piston when it is TDC instead of streight up. So i have to time it manually. The engine desiels when i shut it off, and has a hard time idling when i initially start it up. 50% of the time when i try to accelerate, it tries to die/stall. I manually timed it but, it is about the same. the cam is a 215/224. Carb holly 600cfm singlepump. I almost want to shoot the darn thing, ive been messing with it for a month now. Any help would be appreciated.
