Dennis with Fast Cat cylinder heads is a wizard when running cam numbers to produce some surprisingly accurate real-world horsepower from a Dyno simulation.

Plus, I finally get to share the official cam card for the new 400 CID SBC build! Dynomation 6 was used for the calculations. #SBC #400cid #SolidCam
