    LS1 Cam - Expert Engine Builder Advice Please!!

    Hi, I hope to get some expert advice if a different cam will help. I have a '66 Chevelle with a 2001 LS1, the engine is basically new with less than 5K miles when I purchased it. From what I have read, this cam is designed for boost, which I don't think I am doing. I am wondering if a different cam would make a significant difference in power, or if that's all I'm going to get out of a NA LS1?

    For shits and giggles, if I was going to boost this engine, what would be best?

    Tbh I'd get a custom cam grind over an off the shelf one. Pretty much every performance shop does them. This way it can be geared towards your specific application and mods. If you have no plans of going FI I would definitely swap the cam out.
