motor trouble

[beppe180]

ok guys. i started my motor up today, brandnew rebuilt. started nice and smooth did the break in procedure. went to let off the gas 2 shut it off. it started shakin really rough. almost like its not fireing on all its cylinders. almost wut it feels and sounds like... then changed the coils and pack. still did not fix it. changed wires and plugs no go.. wut else do u think it could b? alittle white smoke came out of the tail pipe not a blown head gasket type of smoke, but i m not running right type of smoke.. i looked at the old plugs and they were all nice and white except for the #1 spark plug insulater alittle brown but not wet with oil or anything.. wut else do u guys think it could b? could out of adjusted valves do this 2? much help needed guys!

Plug wires are in the correct order I asume? Ignition module could be to blame.

yea but 2 ignition modules? one that i know worked previously.. u think the rockers could of tightend up? after alil bit of runnin? after the oil pumped up?
