Using a drop base air cleaner with 3" element in most cases allows adequate hood clearance. GS Ram Air type air cleaners will NOT work.
Other applications that have hood clearance issues are '67- '70 Riviera and '64- '67 GS/Skylark. Please confirm clearance.
*Dominator plenums are CNC machined into the runners. Finishing with a rotary sander is recommended.
