Confused about carbs, need help!
Here is a summits description of the sum-1108 cam. Basic Operating RPM Range: 3,400-7,000. Rough idle, excellent high-end horsepower. Needs 10.5:1 and higher compression, 3,500+ stall, and gearing. 350+ c.i.d., bracket race cam. With that cam you'll want a 3500 or 4000 stall converter. Holley 750 DP and use the single plane intake since you already have it.
