This is where Comp Cams comes in. Camshafts are chosen based on nearly every internal component in an engine, and bore and stroke are huge contributors that decide which camshaft is best for that particular engine, as well as the purpose of the engine. That being said, which camshaft should we go with? One that is perfect for the short-deck won't help the tall-deck engine achieve maximum performance, and vice versa. We considered a middle-of-the-road camshaft that would be fair for both, but it's hard to say exactly where the "middle" of the road is.
The solution: have Comp Cams grind a custom camshaft to suit each engine. The benefits are two-fold. First, maximum performance for each application will be achieved. Comp knows which cylinder heads, intake manifolds, carburetors, fuel type, and octane we're using, and can maximize output based on those parameters for each engine. The other advantage is that we'll be closer to maximizing each engine's power potential, which means big numbers on the dyno.
The profile that Comp chose features 0.580/0.585-inch lift, 236/242 duration at 0.050-inch, and 107 degree lobe separation. The tall-deck engine will feature different specs, but we'll get into that next time. For now, we're at Auto Performance Engines in Auburndale, Florida, to follow along with Kevin Willis as he prepares our short-deck 363.
