My starting line ratio is 16.39, and I drop the clutch at 6000-6600 RPM, and run similar 1/8th mile numbers to you, although I run on 1/4 tracks.It looks like you have plenty of tire,so I see no reason why your consistency should suffer at all, provided you are somewhere close on your clutch setup. I always like to be crossing the finish line a little higher than my shift RPM. Are you 60 foot and 330 numbers pretty consistent now?
