went to the track this past week and ran a 13.4 @ 100 mph. 355 rhs heads comp hyd roller proform vac sec. msd ignition 28X12.5-15 et streets im really happy with the time. Still on a crappy track the re surfaced it the day before so i still had some traction issues. Didnt get time to really tune very much so next time i think we can get in the 12's n/a then ill be hopefully adding a bottle.
