1990 379 36 inch bunk converted to a unibilt. 265 wheel base, 3406b, 13 speed, 3.55 gears, I'm 3rd owner the guy retired and owned it 15 years. It's got a ton of paperwork and has a marine cam, marine injectors, pdi intercooler. Idk what turbo is on it but it's pretty big. The headache rack, toolboxes are already off. The stacks are about 18 inches shorter and all the lettering is off. The only thing I don't like is the frame lengthening it's about 17 years old and is rust jacking bad. It will go under the knife this winter to fix it.
