72 duster 360 NA to 390 Turbo

Got my boost issue fixed. The spring on the boost bleed had gotten pushed into the T off the turbo. Went to the local 1/8 mile track this evening for more testing. It was packed!! Got 2 runs. 60ft sucks, but I made 97 mph. We are on 9 lbs, 12.3afr. Terrible 7.80s hit rev limit on the big end. Air was pretty good. Gonna need to jet up and then add a pound or so of boost. Drove it there and back (48) miles with no issues Videos will be loading soon.
