I have a few more things to add, I have read this whole tread many times. As a Business owner who does care, I'm a bit shocked at whats been said. We all make mistakes and I've made mine before and will again, EXAMPLE Installing Mikes trans cooler, Ran lines hooked it all up looked good, Woke up next morning, Called Mike and said, I Think I made a mistake on Line routing, Went back over it and I could have have done a better job and did. No hurt feelings, few bucks in fittings and we are all good. 2 more questions to Ponder from LMS.
We all protect ourselves at home and business, I'm not a super tech guy but have enough cameras to be safe, I'm sure LMS has the same, If I was under supposed attack I would gladly show all video of dyno pulls, mechanical work etc, Many of my customers get 10 plus pics of issues when doing a inspection for repairs or when any major work is done, Safe for myself and they can see what went down, (example did a timing chain on a 3.5, Here are 7 pics on how clean engine was and chain, guide condition etc) I still would love to see the 1 hour subframe drop as I am jelous.
Lastly I am for sure not a pro engine builder or do I claim to be, but have had my hands in enough to know the deal. So On Mikes engine, It is stated that aftermarket bearings were used clevite from my understanding (not a bad brand but definately not what form specs call for). I do know The Ecoboost Crank is not meant to be remachined, Being said Ford uses color coded bearings, Meaning Each bearing pack is specific to measurement from the factory so they can fine tune each bearing, Now Building a high performance engine I would expect the same set up. The fact that one size fits all bearings were used just drops my jaw, Especially as Ford wants to build fast and cheap.Lastly I would love to hear how after 20k of use your bearing clearances (besides spun ones) are still too tight? If they were loose It would be easy to explain, wear and tear but If built wrong
Just my opinion but This motor only held up because it was not beat much and well maintained. Lets be serious, Mike is not a Drag guy or a Street racer, So A weak build would hold up to someone who makes the here and there pull an a on ramp or stoplight. Not enough to heat up the crank and bearings, A loaded dyno pull is way harder on any motor. Looks like he just had luck on his side as a daily driver
