need help with a motor swap
 

hey guys.... i bought a chevy duramax 3500 4x4 with a bad motor, production date is 7/05 and engine code is 2. i found a wrecked 06 GMC 2wd which i beleive has a engine code D ....will theese motors swap out with any problems?

If you plan on pulling one and dropping in the other :nope: ain't gonna work without a computer and wireing harness swap, plus possibly still some EFI Live work.

Actual short block to short block, :humm: don't know for sure but it might work. Can't remember if the head bolt pattern changed or not. I don't think it did.

thanks for the reply.... i got some more info yesterday... i,m buying the whole truck to get the motor and it has a #2 engine code also so i think i'll be OK. i the olny thing i can think of now is if the oil pan is the same going from a 2wd to 4wd? which i could swap if need be...so i will have the ECM and harness if it comes to that. thanks again
