Re: New Carb - Whole new ballgame!
I had an Edelbrock 600 on my .060 350 when I bought it. I added a Trickflow top end kit. It was an improvement over the smog 882 heads and performer cam. I jetted the carb to its max setting and it still seemed blah. I put on a Holley 650dp and noticed an improvement right away, but it still needed some tuning. I got it close, well I thought I did. I mostly tuned out a lean stumble I had and I thought it ran great. Then I took it to the dyno. I was lean in the secondary and I still had a slight stumble on part throttle cruise. I slowed my advance curve down and rejetted the carb. I went back and made another 11hp, however, I'm still lean in the secondaries according to the Air/Fuel readings. I went up another two sizes and it runs so good now. There is nothing like the feeling of getting the right carb dialed in.
