I just did a Ford 3.5 in a Ford Edge. I had to break it up so can't attest to flat rate time, but had to pull the upper intake, both valve covers, the HUGE passenger side engine cover, the engine mount, and the primary and secondary cam chains. And two bolts hiding at the very back for the air conditioner compressor that uses a stretch fit belt that's an absolute ***** when you're working by yourself.
And it dumps oil all over your driveway when you pull the side cover.
