So I’m going to be getting a HO Alt for my 2009 F-150 (4.6L 3 valve). Mechman has a 240a for $399. I reached out to Singer and have a list of options but would likely stay from 220a $449 to 240a $469. I will need a new belt and possibly a smaller pulley both day. Any experience with this engine? Also, which would you choose? I’m leaning Mech for the price. Both have been super responsive and great to talk to.
