Does anyone know anything about late model 351w truck engines? I just put a '94 351w in my 68 fastback and it's extremely out of balance. I have a 50z harmonic balancer with a matching flywheel, but I was told by someone recently that late model 351 windsors are internally balanced. Is this correct? If so how do I go about fixing this issue?
