Answer:
you need to loosen the hold down bolt on the distributor and while you or a frind hold a timing light on the harmonic balancer (located behind the crankshaft pulley) turn the distrbutor clockwise or counter clockwise until the timing mark is correctly located on the marker attached to the block.
you can do this by ear by listening to the engine and if it is backfiring out of the exhaust while cranking the timing is retarded and u must turn it clockwise and if it backfiring out the intake manifold you turn it counter clockwise to fix it and do this until the engine is smoothly running than re tighten the destributor hold down bolt. this is not so exaact tho because you may not have the engine firing at the optimal time.
