i've been thinking for awhile now about swapping the old 350 for a diesel. my goal is to improve the fuel economy (anything is better than 6mpg) and have some torque for pulling.
current setup: 8" lift all suspension, 35" tires, 4:10. stock 10 bolts front and rear.
from what i understand the 4bt will work in these k5s with some modifications. the ones i have seen are almost all manuals. from what i also understand the automatics are not enough to handle the torque.
what would be the best way to go about this? as far as a donor vehicle? what tranny and transfer case would hook up to the 4bt. i currently have the turbo 350 and the 203. i believe adaptors are pricey and having a manual would be kinda cool. i've also heard of 20+ mpg.
can anyone offer incite?
