i have a 89 k1500 with a carbed 350 crate motor. when i converted the engine to carb and hei the timing marks and crank no longer line up. i know this could be solved by purchasing a new pulley but to be honest i dont have the time or money right now. i have been playing with the timing for a month now and cant seem to get it right. its always too fast or slow. i was wondering if you guys know a way to time an engine without marks an get it right. i need some help for a quick fix. please help me out. thanks.
