Re: 350 TBI? Switch to TPI or leave it alone?

OK... Heres the deal guys.... The motor is out of a 94 gmc and it is TBI... I am building a motor to go back into the truck... This is just the only forum that I could find anyone that had some knowledge about these motors... I am doing a complete rebuild and making it a 355.. I am just wondering if I can get more torgue and HP out of a TPI than I could a TBI or if it is just a waste of time? Dont hate us truck boys... Thanks in advance... BTW I am going to be using the trailer mainly to poull enclosed trailers iwth, anywhere form 12ft to 20 ft.. Thanks again...
