454 in a CUCV, M1009 Blazer
 

I picked up an '85 military Blazer with 103K on the meter. The starter is out of the 6.2 diesel and the reverse is out of the trans. I need to pull either the motor or transfer to remove the transmission, so it might as well be the diesel. I have a nice 454 out of an'80 RV that is 245 horse. Thinking of freshening it up and dropping it in. My questions are, Do I need a donor truck for the wiring harness, will the exhaust bolt up to the BBC and will the 3 hose power steering pump from the diesel mount to the BBC? Basically, have you done this before? Thanks

Haven't done this before (I prefer the diesel),but I know it will bolt in. I would use the 454 wiring harness to make a clean factory-like job,but you can wire up whatever you need off of the diesel engine bay harness. You'll have to run a feed to your distributor. Both are single headlight vehicles,so that's good. Not sure about any harness connection differences between '80 and '85. The 6.2 exhaust bolts right up to either the small block or the big block exhaust and I'm thinking it's the small block (could be wrong). The power steering is hydro-boost on both so you'll have easy interchangeability. Pretty sure the pump mounting brackets will have to be BBC and everything else will work. You have the big bad radiator you'll want,too. You'll want a BBC torque convertor due to the different power band between engines.
