Any 90mm tb will work but you will also need a TB spacer.With out the spacer,the thottle cable cam hits the manifold and does not allow full trottle.ETP sells them for like a hundred bucks.I just did one with a ptm92 mm tb to a ls7 intake.Works real good and also has holes to mount your cable bracket.

My Holley worked fine. No issues whatsoever with clearance...
