I am thinking about getting an Edelbrock cam and lifters for my small block 400. It is basically a stock rebuild with K&N air filter, edelbrock performer intake, and hedman torque step headers. I am looking for low end power. According to edelbrock their cam with my engine should produce about 390 ft/lbs of torque between 2500 and 3500. Does anybody know of a better cam for my application and low end power? Thanks, Mike.
