Not all stock, but nothing special right now. Stock H/C/I on a 306. I didn't even see a need to do any tuning w/ the tweecer for that. Hasn't been on the track but I wouldn't expect much more than 9.5's in the 1/8th. W/ twisted wedge heads, GT40 intake, and a .540 lift Lunati it would run 7.92 @ 97. Wish I hadn't sold the intake now. Got everything else I could swap back on and wake it back up. The wife even says it's boring now.
