    My new harness is in the works at Nelsons thanks Allen and Roy for leading me the right way. Hope to get it this week so I can get it fitted up and then pull the motor out for cam ,head and converter upgrades

    This is a healthy 6.0 NA correct? I bet you could get away with stock TBSS injectors without any issue. I believe they are 33lbs. You can get them with adapters for less than $100 usually.

    Shooting for a little more than healthy LOL but NA yes .Allen is suggesting 36 to 50 lbs.Would rather get a little big for future upgrades .He said tuning will be no problem with the bigger injectors.

    12613412 injectors 50lbs

    I purchased a set of these used from a forum member for 140. they come on the 10' and up 3/4 ton + trucks with the 6.0's. they are about 2mm shorter but fit and work perfect. they have the ev6 style connector though so you will need adapters which he made for me for 40 bucks/set.

    Idk if this helps but I thought I'd just throw it out there as an option since you can probably grab them pretty cheap used online or from a jy vs more expensive aftermarket ones.

    FIC is the way to go if you are gonna buy new. Otherwise I would cruise the classifieds on LS1tech/pt.net.
