    I think it made like no difference with under a 500hp engine
    In fact, they questioned the real value of a cross over pipe at all......

    thanks, the Camaro was supposed to be the mild car but it sounds and idles nastier than the vette

    I ran the Comp 270HR for the first 1000 miles when the motor was first built and kinda wish I would have kept it. It was perfect for the TH350 auto at the time and made 16 in of vacuum with a clean idle able to support a/c. I don't have the Vintage Air system in my car operational right now but already anticipate having to run an idle compensator
