What's the best off the shelf cam for a N/A 302. I want one that will make me a good amount of horsepower and I want good midrange power. AKA not all the power at 7000rpms. Don't say FTI cam cause I'm not sure of my combo yet and I dont want to get one custom made that wont suit my combo later. Also, can you breifly describe what is needed to put it in. Thanks.
