In late February, I received and installed your Rochester Quadrajet Stage 2 after rebuilding the 350 in my 1980 Camaro Z28. It ran awesome right out of the box. The only adjustment I made to it was to slightly increase the idle speed. There’s no stumble or hesitation when I step on it; the metering, jetting, and air-fuel mixture are perfect. I highly recommend your custom tuning services and products to anyone – it is money well spent!
