    Hi Everyone. New member and new post. I apologize if this is out there somewhere or if I am posting in the wrong spot. Spent lots of time looking and thought carefully about where to put this.

    I have just completed a 2016 F-150 engine swap into a 2011 Mustang GT (due to blown engine). The 2016 engine has only 7000k (~4400m) on it, but has been sitting for a good 3 years. Oil film is present on valve train and engine spins with breaker bar on crank - no issues. Just wondering if there are any special procedures I should follow before turning the key? Thanks in advance!

    I'd suggest priming the oil system before firing it up

    side note - how are you adjusting for the differences in the motor and engine management from the two chassis?

    To prime it, you would have to turn the crank. So I you want to do this, pull all spark plugs and crank it over for 10 seconds.

    3 years is not that long IMO, I would just start it.

    Or pull the fuel pump relay and crank the engine over for 10 seconds. It's quicker than pulling out all eight spark plugs.

    Well, if you dont pull the plugs you are putting compression pressure on the bearings. That is somewhat pointless, just start it then.

    Thanks for the replies everyone! The local mechanic I've been talking to about it also suggested just starting it, letting it come to temp while ensuring I have the air out of the cooling system. I was going to disconnect the coil packs and injectors and turn it over, but good point about the pressure on bearings. I'll follow up with my final chosen approach.

    As for the side question about how I'm doing the swap, I have one remaining question, but I'll create a post in the swap section describing what I've done and asking for opinions. Thanks again!

    I hope you addressed the gen2 gen1 differences. Not sure when the trucks switched to Gen2 engimes.

    I bought a new Mustang GT in 1986. When I went to Okinawa for a couple years, the Ford dealer recommended spraying a squirt of oil into the cylinders before firing the engine. I had no problems.
