It was also dynod with the 2" chassis headers he runs on the car and bischoff had a short 3" exhaust setup attached to it.

Typically dyno operators run a dyno header on there similar to sprint car headers which will inflate the numbers a bit more

That's what I was thinking, 4.75 stroke. What was the lead time on that crank?
