so i got a fresh 327 with flat top pistons and 462 camel hump heads all good, just need a cam. Im thinking around 282-286 degrees of advertised duration and around 470-500 lift, if i can go more duration i will. Ive read other threads of people recommending somewhere around 268 duration. are you kidding? come on, I'm a 16 year old punk with some serious testosterone and need this engine to be a good fit.
