As far as set-up on that era chassis in general a good base line is a more balanced set up. 56% left, 56% cross, 45% nose, If front is adjustable
2.5 RF neg camber, .5 LF pos camber, Even if it's not adjustable I would be sliding an old axle over spindle shaft and setting camber by hand If it's off by more than .25 I would be tweaking it. As far as these chassis needing low front stagger I have no knowledge there, 1 1/2 " rear would be close for Naugle, but once you get chassis set - up right would be a little to much for Blairsville.
If when you ran 11's right after rain plus If they were new not prepped up enough that still could have been the push, Blairsville not only is prep a must the track is prep sensitive the right mix can make a huge difference, Blairsville most run 33's prepped down,
Pedator racing is all about momentum Gearing, Roll speed, very smooth on wheel, throttle control is key as far as gearing you will run 2 for sure Avg 3 some places 4 front driver sizes bigger than SR Clone.
