I will agree with you on the carbs if he is going to have port work done.From what I gather he is after either/or.Not both.I know from experience from people running 26's ported versus unported with 28's that the 28's will out run them every time."I know different port jobs will effect the outcome to this and the persons ability to tune there set up correctly also"For example,I had a 04 that ran t-5's v-2's and 28's.My buddy had a 04 also same pipes and reeds but had porting done to it but had 26's.We both weigh within five pounds of each other and the same gearing.Mine would pull his every time by two lenghts.I,m not trying to get into a argument at all just trying to explain my reasoning for my .02 cents to him. :beer:
