1979 K5 Blazer 6.0 LQ4 out of a 2005 Chevy 2500 w/ 85k SM465/NP205 1 tons axles Dropped the old fuel tank when putting the shackle flip on, probably gonna trash it cause it's pretty crusty and new stock replacements aren't too costly. Threw the fuel cell in the bed idea around for a little while but I'd like to have that bed space available for other things. Idk if it matters or makes a different but the wire harness that I aquired with a complete intake and a lot of other stuff (DBW pedal etc.) The whole shabang was pulled from a 5.3 flex fuel engine so I don't know if that changes things, the computer was tuned near stock, VATS and all the other non essential stuff deleted, fuel and timing adjusted a little bit... something to let me get it started and running then more in depth tuning from there. I would like to know what combo of factory replacement parts and aftermarket (I know a lot of guys are using special fittings and such) will net me the best results and not be too costly. I've searched around and read a lot but I am looking for a combo of parts that will be reliable, trouble free, easily replaced parts at the parts store or places like rockauto and let me drive worry free not having to worry about keeping at least 1/4 tank of fuel in the tank at all times.
