I ran the old motor again this year (451” 10:1). It did improve to an 11.51 @ 119.78 besting all the 383builds before it. New motor spun a bearing on its first outing. Culprit was loose lifter galleys and a too inattentive driver. Once it got warm the oil pressure went down the drain. Maybe I’ll get it out next year, maybe I’ll work on putting the little motor into the 11.20s.
