Another 454 Vortec Build Thread - Documenting, Q&A, Help

New injectors, plugs, wires, FPR, Dist cap and rotor installed! Ran much better but still getting a little chug and backfire so I pulled the pump yesterday and am installing the new one this week. With an entirely new fuel system and mostly new ignition system this thing should run much much better! Have a WAI on order as well as new headlights. New will be replacing the roof lights and a led panel with 8 lights to the bottom of the front bumer, then on to the front suspension and all new brakes. Still have to replace then windshield, and figure out the passenger seat issue as well as putting in a radio. Have the exhaust parts in the shed so either got to mock that up and clamp it and have someone weld it, or I have to pay like $400 to have the muffler shop fab it up and weld it. Wife wants some meat on the shoes so we are looking at 20's with some 65 sidewall height tires in the near future as well. she's slowly coming together but lots of work to do!

Finally had time to get the new fuel pump installed into the bucket and wired up. Once this is installed this weekend that would make for a brand new fuel system, and brand new ignition system! Have to pick up an air filter that I noticed missing as well. Here's some pictures of what I was working with. I know I need to clean the top lol. The fuel vapor sensor is just sitting on top and not really being held in by anything. Might pick one of those up as well if I can find the wiring that seems to be missing from the loom. Will post a pic of that later when I get home as well.

The EVAP sensor is held in with a barbed o-ring just like the MAP sensor on a 350, it's good to go. 2500/3500 trucks didn't use that sensor so your truck won't have the wiring for it. That's a 1 size fits all sending unit.

Beautiful thank you sir?

If you haven't already replaced, the front O2 sensors would be on my radar also

10-4 gonna replace those and add the 2 back ones back in. Still driving like crap but think it could be the sensors or the lack of exhaust. Also need oil in the rear diff so gonna check both diffs t-case and tranny fluid.

Are you aware of making sure the distributor is set within the proper limits of the cam offset/retard specs? you will need a scan tool to check and adjust as needed. If it is way off it can effect performance.
