Chief 6.4

Current Drag Pak Engine Question:

Well any I suppose. My school is doing a Gen III project and we would like to add a drag pak cam to it.  We have a vvt block, but we have the capability to use a non vvt cam if needed.  ( we have an adapter)

What cam is used in the drag pak cars?  Any one have part numbers or a place where I can find specs?

You don't know the duration at .050" by chance, do you?

That's what I was thinking, but was wondering if you knew. I'm not sure calculating it is possible, I think it would have to be measured as ramp speeds can be different from cam to cam.
