That's fine, because I believe that will improve low-end torque and also mean a smoother idle compared to a hotter cam with a smaller lobe separation angle. I know that marine engines are cammed with less overlap. Will using a cam from a sbc intended for marine use be a problem for me in my El Camino? I have done some research, but I can't find a definitive answer. I made sure to keep the lifters in order so that they are properly paired with the correct cam lobes. Like I said, I had a reasonably low-mile/hour cam from a bad, HO 305 (225 HP, factory quadrajet, it has a tag on it says Volvo Penta AQ225E NO CU62799). Here are the details to what I am working with: 1964 327, 0.030 over, 1963 327 heads 1.72/1.50, GM squarebore intake with 1964 Rochester 4Jet carb (predating the Quadrajet), Jacobs electronic iginition.
Many thought that was awful luck, but I preferred to think of it as the perfect opportunity to finally use some extra heads I had on the shelf, and recycle cam, lifters and timing set from a High Output Marine 305 that I was given a few months ago (in El Paso, nobody winterizes. Recently, I had the pleasure of experiencing a sunken valve seat on a many-mile 327, with original heads (non-hardened seats).
