We have run B1, Indy -1 345CNC and OOTB -1 heads on the car. The cam in the 345 head and b1 heads were similar. The 345 head went 4.80's here in Vegas in GOOD air for here.

FWIW we run a MUCH smaller header as well. I know you know this but in a dragster with a glide the converter is gonna make or break the deal. We try to get to 6-700rpm drop on the shift. We have been 1.02 60' here in Vegas as well on a little bubba.

The entire car is apart now and we are redoing it from end to end. Also building a new engine, hoping we can go .50's here, not sure we will get there but that's the goal.
