road car cam for my 318

I have been working on various tuning approaches and have met with marginal improvements but nothing that solved the issue to my satisfaction, but THAT'S NOT WHY I STARTED THIS THREAD. I started the thread to ask about the best cam to suit a particular use for a specific engine in a specific car. If you want to change the subject - START ANOTHER THREAD. Why would you think that this thread is the only thing that I am using to solve the problem. I think it is much more productive to talk about dealing with tuning issues with knowledgeable folks that can actually see and hear the engine run and drive around with me. SHEESH!
