I ran a PTC 9.5" nonlock 3500 in my GN.....went low 11's on 20-21# of boost and pig rich. I think it could have been a little looser....say 3600-3700...to really make the car come alive, but it worked for what I was doing.
I have a 3400 single LU vig. and went 7.30(1/8)on a full weight stocker with only a cam swap and alky. Recorded 31.8 lbs of boost through the traps with 5 degrees of KR. All on pump gas and 10" MT's. Car still drives like it had the D5 in it.
