None really, runs really strong and still pulls 19 vac with no smoking or blow by so far. We even ran it hard for a while on a faulty F/P before realizing it was at over 14 : 1 A/F's.
I dyno'd it friday at the identical settings at the strip and she did 281 hp and 265 ft/lbs. After pulling a ton of fuel from the top end I finished at 302 hp and 265 ft/lbs. All the power gains were from about 5,500 to redline. I gained at least 20 hp from 5,500 - 7,000 rpms and almost 30 hp from 7,000 - 7,800 rpms. To bad the drag strip is closed till next year.
