For a 368...maybe, bigger than that, yeah, I'd get rid of them along with appropriate cal changes.

For the record Hib I had Marc remove mine on my '95 when he did his porting. I never had a driveability problem and the engine always seemed to have plenty of torque. Of course there were several variables involved besides the elimination of the secondaries. But I was happy with the way the car performed around town and on the track. --Bob
