If you do the work yourself that number is still way off. A good 2015 F150 5.0 with about 30k miles goes for around $3k on LKQ. That with a used 6r80 ($1000) accounts for most of the cost. You will then need PCM ($150), Motor mounts ($100) , engine harness ($250), alternator ($60 used), ac compressor (about $200 used), and misc hoses and connectors. I am not accounting for an exhaust system since that can vary wildly depending on setup.
Mostly looking at it for the aluminum block... An aluminum SBF bare block is $4400.... :eyebulge:
The draw to it for me is that I could build a 427 stroker with the aluminum block and come in at about the same weight as our V6 when done. That would be an awesome combo... In order for a coyote to hit the power numbers a 427 can NA it would need a supercharger. That easily adds 120lbs on top of the ~430lbs coyote. An LS is about 400lbs.
The V6 and 5.0 transmissions have different bellhousing bolt patterns unfortunately. Other then that though they are largely the same. I could just make an adapter plate but with my trans having 108k miles on it I would rather just swap it out for a lower mileage replacement.
Haha yea my warranties are long gone! 108k on the clock currently which is why I am looking at engine swaps vs turbo/supercharger setups.
Yeah but at the same time if you stay with the 3.7 which 108k miles isn't a lot but you can pick a low mileage one up for 800 dollars usually.
