Official Dyno report with this cam choice, Bravo heads, a dual plane intake, a Brawler 850 carb, and an HEI distributor. This cam produces an immense amount of torque in the low rpm range. We highly recommend this cam for applications requiring very high amounts of torque in the low rpm range.

If you would like expert cam recommendations for your engine, contact us through the "seller information" tab with the information listed below. We will tell you what cam is best suited for you. Running a cam that is too big in a given combination is not only pointless for making increased power, but creates a increased loss of drivability and unnecessary wear on the valve train. You must have sufficient cubic inch and/or compression ratio, coupled with correct size cylinder heads that will allow enough flow, to justify a particular size cam. Bottom-end and mid-range performance are always affected when you increase cam size, but it would be affected even more if a cam selection is over-sized to the point that no top-end power is gained. So choosing too large of a cam becomes a two-fold problem. Tuning also becomes more difficult with larger than needed cams.

For a recommendation on the best cam for you, please contact us with us the following information:

  • Vehicle model or weight.
  • Engine size, (cubic inch)
  • Approx. compression ratio.
  • Cylinder head runner size.
  • Single or dual plane intake, (if dual plane, what model)
  • Final gear ratio, and overall tire diameter if known.
  • Transmission model.
  • Converter stall range.
  • Your hp expectations, and how you will be using the vehicle (cruising, street, strip, show car, etc.)
  • If a lopey idle is highly desirable. The size engine you have determines this with a given cam choice. We can tell you exactly what a particular cam will sound like in an engine.
  • The brand and type/series of lifters you are running. Very important!
