Dean Lampe and I both had 427 engines built by a guy who had a great reputation with FE engines. They were both run in by him we thought however the truth was his young "interns actually built our engines and ran them in with standard Valvoline 2 w 50. We took deliver the night before we were to go to a race (basically just enough time to get them installed). Both engines granaded within 10 to 15 minutes on the track. We know about proper breakin
oil and procedures. We were much younger then and took people at their word...not so much anymore.
The Coyote is a whole new adventure for me and I am learning more each day.
