First race completed on moded argus yesterday night. Engine ran flawless all day and very fast. Had a blast, fuel mileage was great even being fat. I could go almost 8 mins on a tank at close to flush settings... Vey pleased, job well done Lance! Engine has a very linear power band, defanitly the smoothest engine i have ran. Even spectators commented on how smooth engine sounded and ran. For the price of engine,mod, and proper pipe you cant beat it!
