Hi,
I am knees deep in working on Coyote swapping my 08 V6. I got all the important stuff figured out, and am currently stripping the car. I am dead set on going with a 2011 - 2014 ECM (preferably 2014), so keep that in mind. Also, I have no fixed budget, and I am doing the swap for my personal fun - a lot of decisions are financially stupid, but fun.
My original plan was to build a "OEM+" 3-2-1 Coyote. So a fresh built gen 3 block, maybe some sleeving and slight overbore to 5.2L. Then ported gen 2 heads with oversized valves, and finally mostly stock gen 1 timing components, with some upgraded components here and there, like improved tensioners. I have to go with a stock camshaft tho, due to regulatory limits (emissions) in my country. Rounding off the build are some nice later model components, like a 2018 intake manifold, a 2020 GT500 oil sump and pump, etc. Stuff like that. Makes a pretty solid Coyote build in my opinion.
Now something caught my attention. The Ford Performance M-6550-M52A camshafts. While they are long gone, the idea is that these are basically gen 2 coyote camshafts spec wise, with mounting points for gen 1 coyote timing, fitting a GT350 head (so no flat plane magic). This is noteworthy, since you can install Coyote gen 1 and 2 camshafts with modified MMR rocker arms in GT350 heads, but these M-6550-M52A camshafts basically mean running gen 2 camshafts with gen 1 timing - which is sweet. The question is now, if I should switch my plan here, and use a combination of 2021 GT500 heads (drop in replacement for GT350 heads) with M-6550-M52A equivalent camshafts. It would add some novelty to the build, but introduce some challenges, too - like ensuring piston/valve clearance, etc. - I could switch the block to a GT500 block too, but I don't think its that useful.
You might be wondering why I even consider this, and not just go with a good pair of custom camshafts with my original build plan. The reason is that I am heavily limited by emissions in my country. I have no definitive numbers, but think California. And camshafts are a major factor in emissions - hence my worries to deviate from stock camshafts. I would presume that the mentioned camshafts are pretty much emissions legal, with them basically being gen 2 coyote camshafts in a special packaging to fit in GT350/500 heads.
So - opinions?
