I have a 93 5.7 motor. I am going to replace the tbi with a accell super ram unit the system is not complet ( I only have the runners and the plenum) I would like to buy a complet tpi system, it is my understanding that the super ram runners will bolt to the stock tpi manifold, if this is true is there a certan year that I should look for to make this converson work? I will try to buy a tpi unit with injectors, fuel rails, distribtor, etc...
