Yep, in fact i have 2 sets right now, (1) 2.9 maniflod, and (1) 3" complete ready to run, setup for nitrous also. They are pretty much like hilborn or Kinsler, same tuning charistics.
Ron's fuel injection bought all their spare parts and the guy that used to run the Crowers' fuel injection shop still make nozzles at home (cheap).
What's your question?
