Run Notes: 1) Through the mufflers, bad bog off the line, 87-octane fuel all runs, 2) Still has slight bog off-line, 3) Good run, but car stumbled at half-track, 4) Really, really hot out now, less timing does not help, 5) No pinging, but timing advance seemed to hurt performance, 6) Wow! Car left nicely and pulled hard all the way through.
