I got a 2003 HD F-150 and I just ordered some longtube headers and before i wanted to install them, i wanted to order me a lower pulley and change my plugs and get it tuned, but i was wondering what size pulley to get and upper or lower or both. It is my DD and i dont want too much boost or stress the block. Any help would be appreciated.
Also, where can i get a good set of a pillar and gauges from? Thanks again in advance.
