      DBC throttle body for whipple 2.9?

      68 Camaro LS swapped.
      Sleeved 6.0 Aluminum block 388 cu in, stock stroke.
      2.9 whipple with 2010 Camaro/Truck accessory drive alignment.
      ATI 10 rib accessory drive pulley on order to be installed.
      For break in purposes will run 6 rib 4.0” blower pulley then swapped out for 3.5” 10 rib.

      Current issue:
      Edelbrock Victor LS series model 3864 Drive by cable Throttle body with passenger side throttle blade cam does not clear S/C pulley.
      https://www.summitracing.com/parts/e...SABEgJ5kvD_BwE

      Attempt to flip it upside down will clear TPS but not IAC.



      1. Is there a spacer that will extend throttle body out and or twists to clear IAC and if so will it work with 10 rib blower pulley?
      2. Is there another Throttle body option with spacer to accommodate driver side, drive by cable and clear 10 rib?
      3. Is there a driver side throttle/cruise cable bracket for above mentioned option?

      Whipple sells an extension for more clearance.
      It's about 1.5" thick as seen in this photo.

      I called Whipple & they hooked me up with the part.
      I could not find it on their website but ask them for a 1.75" spacer.

      Wound up adding communication cable to xmax ecu, elec TB and and pedal assembly was almost the same cost, plug and play was a no brainer.
