What's a good cam/cam grind for a nitrous slant? Stock compression, offy intake, hooker headers, drag car only. Really don't want to be revving it to the sky though. |

With N2O you want a little more exhaust duration and an earlier exhaust opening. This means a single pattern cam rather than one with more intake duration and wider lobe centers. With stock compression I would go for something around 220-224° duration at .050" lift and 110° lobe centerline. You can up the duration a bit with an overly loose torque converter, but hitting the nitrous off the line makes this less important. If you are going to run a plate with a spray bar I would turn the carburetor and plate sideways. That is the primaries will be towards to head or fender rather than the front. Use an open adapter/spacer on the manifold rather than a 4-hole. I would also suggest a progressive, RPM-based, nitrous controller so that you limit the low end cylinder pressure and torque a bit for engine safety and possibly traction. |
