Glen. You’ve got sharp eyes in spotting the Y entry in that run schedule. When the engine is uncrated, the Thunderbird covers I plan on using will be the first indication that not all is as originally submitted in the entry form. Using a different engine than listed on the entry is still legal as long as the engine actually being run still fits the rules so I'm covered from that standpoint.
Although this years Y entry is likely not going to be a top place contender, it’s definitely much stronger this year with the aluminum heads than with the oem iron heads used in last years combination. But regardless, I’m looking for this years Y combination to be much higher up in the scoring than last year. With a considerable amount of dyno time available this year, I was able to tweak on the tuneup and concentrate on the 2500-3000 rpm range heavily and work on getting the score higher in this area. I've sacrificed some of the top end numbers to help the overall score for this year. Plans are to run the engine one last time on Thursday morning to try out one more idea that Geoff Mummert (John’s son) has suggested. I’ll add that Geoff has been extremely helpful this year on ideas and suggestions that have helped to fine tune the combination with the aluminum heads. Thanks again Geoff.
