TST Products, Inc.this site has some after markets parts for big rigs not completely sure if they have anything for your year truck though

 

Normally a 91 wouldnt come with a P-pump. Only needed a gear, hub, and adapter. In any case, there's a how-to in my signature line. Same deal as a 466. If you're looking for more than 30-40hp, then dont do those mods just yet. Pull the pump, and take it to a good injection shop. Basic rule of thumb is 1cc for every 2hp. If you want 100 more hp, tell them to get 50 more cc's out of it. Then you can dial it in after it's back in. Timing should be 17 for stock to light fuel mods. Go to 19 if you max out the stock pump, and tighten the gov springs. You can go up to about 24 with higher rpm and steep gears, but popping the headgasket is easy if you're not a diligent driver. Turbo is ok for the freebie mods, but time to upgrade when you go past that. The 360 is a super tough little engine, it'll take almost anything you throw at it.
