Hey everyone. I need some help over here. I have a 89 k1500 with the 350 in it. I’m about to buy a 87 454 that I’m going to rebuild and put in there. The motor is coming with the ecu and wiring harness. I need to what I’m gonna have to do to get it out I’m my truck? What transmission with overdrive is the best bang for my buck manual or automatic? Is the radiator I have gonna be powerful enough(it’s a new rad but the same as stock)? What size driveshaft will I need or will I have to go to a driveshaft shop and have them make me one? Will my current transfer case handle 4-500 hp and torque(it’s stock but if I can keep it I’m going to rebuild it due to me not being able to get into 4hi)?
