Mark it sounded wonderfull in the shop and putting it on the trailer, With the choppy idle it was hard to tell till I hit the track and the dang thing would'nt rev. The points battle was close enough that I went ahead and ran it anyway (very poorly I might add) We pulled it apart the next day and found my mistake along with 8 burn't exhaust valves and 1 cooked piston. Lost the championship that season by 17 points....
