Re: Copo Automatics... all had pollution
When I bought our Chevelle, the first thing I did was remove the AIR manifolds and pump. There must have been a slight misalignment issue because I started rolling belts at higher rpms. I put just the pump back on and had no more problems. There was no noticeable power gain any way. The addition of headers made a seat of the pants improvement. I'd put my money on ALL COPO, L78 and L88 cars having the AIR pump in '69. Just a personal opinion.
