I’m at a point where my engine is in need of a inframe and injector set something fierce. While in the process I’m going to swap out my direct drive fan for a fan clutch, my log manifold for a new style pulse manifold, and my turbo for a ht60. I’m going to get new fuel lines (I think they are original to the truck, 39 years old!) and have my pump rebuilt and turned up a bit. I don’t really have the time or money to do a out of frame rebuild. Will the stock bottom end with new bearings, sleeves, rings and pistons hold up fine with a little more fuel and air? Info on these bc1 engines is fairly scarce, not much is out there. Also if anyone can think of something I should do while in the middle of inframing the old gal I’m all ears.
