Just chiming in... I built with a Coyote and purchased the Complete Kit. I would probably do this again, BUT, there are a number of parts that aren't used, and a whole bunch that are still needed that aren't in the Complete Kit. I think this is probably a general statement, and not specific to building with the Coyote as the engine. I actually thought the complete kit would have 99% of what I needed, but that didn't end up being the case. I have a big binder full of receipts for parts to prove it!
