For your consideration, attached is a picture of a "cross-ram" EFI IR intake that Lance Nist brought to a recent Pantera Club meeting here in So Cal.
Lance also has his own line of "Pantera EFI" ECUs.
Haven't seen many of these intakes on Panteras, but could be an option to have both longer runners *and* visibility out the rear. (Although may not fit w/180 deg headers.)
Is this the Borla/Kaase 351W intake or the infamous Australian intake? Have you actually seen one on a Pantera?
