I have been 9.90s on pump gas NA.with that head out of the box. In a 3400lbs car and a 4.10 gear.
Care to share the combo with everyone?

Very very nice finish on those for a cnc head!
Thanks Glenn, the Dart 227cc Pro 1 is a VERY NICE HEAD

As of now we are waiting on the last set of CNC'd heads, Want to mock them up yesterday but no head = no mock up

I do like the fact they are now thinking of guys who would like to run a Stahl header pattern ;)

690ish HP, on pump gas with a small block. I would be interested in this combo. Especially with a box stock head?
