  1. Running rich?

    Engine
    Hey guys. Bought a crate motor about a year ago for my project car.

I'm assuming it's running rich because the whole "eye-burning"...
  2. Rich idle

    Engine
    Hey gents, I have a new crate 383 with a Holley 750. They set the carb at the factory base don their altitude which is about 2,000 feet higher.

  6. Holley 600 Changed Jets runing rich

    Engine
    I was running my 68 Camaro V8 350 with Holly 600 at hi alltitude (5500 ft) and it was using 63 size jets. I am now back around see level (0 to 1000) feet. I noticed that on acceleration it was a little choppy so I changed back to the stock 66 jets. Earlier today my friend was following me and he...
