You didn't use race gas in it for the dyno ???

Dave,
Thanks for the input - thought I was OK at 36 but just wondered. Had seen on some Mustang forums kids talking about 40 degrees, but running pump gas, even what they call 91 octane, is a bit questionable today.

Pat,
Yes, the damper was verified at the machine shop and TDC "0" marked with red paint to keep me straight.

Jerry,
Good point on the heat range. No, we did the dyno runs on the same gas it will run on the street, 91 octane pump gas. May not be right, but that's what we did.
