Q: Will a duramax fit in my truck?

asked by on October 05, 2016

I have a 2004 gmc sierra 1500 with the 5.3 vortec. I have a friend that's willing to give me his old truck that's a 3500 with the 6.6 duramax. The body is wrecked on the donor truck but everything else is fine. What would have to be done to swap the 6.6 into the truck with the 5.3?

My car has 310000 miles.
My car has an automatic transmission.
