yes I was involved but did not assemble or machine. Charlies crew did all that. He does almost all of my machine work. Having dynoed all of my engines at Charlies over the last decade or so I can tell you that it is not a happy dyno and we have backed up almost all of the numbers it posted at the track. People have been telling me for 25 years now what Indy headed motors will or will not do. My friend Larry was a big part of what success we have had and yeah he worked on these. That dip in the numbers has happened on every motor that we have tested there. It is a glitch in the software and yes Charlie knows about it and had had the manufacturer look at it several times. The combination was simply reusing some existing parts and marrying them up with some new stuff. Yes it is a 540 (4.25 stroke 4.500 bore) . All I can tell you is that over the last decade and at least 30 to 40 motors tested at that facility the numbers have proven to be reliable data for me.
