Ok, long story here, I have a good friend who has a glider kit with a 1LW 3406E 435hp that is looking to get better fuel mileage. I will provide arraingement number and other things as I get near the truck again. I know it has a Borg Warner charger but can't verify part number of the charger
to determine which housing wheel ect. Complaint is barely 5.4 mpg, low power ect. Does anybody have a parts list for say 550hp and 6.5-6.7 mpg. Not looking for a knock down power house. This is a fleet truck with a fleet driver. He has considered swapping in a 60 series that I have built him (BK60 500hp) but I am dead set at getting this Cat
up to par. I believe it has 57' injectors in it but that's about it. Any advice on which cam, cylinder kits, injectors and files would be greatly appreciated.
