Hi, and welcome Slant6225Valiant73. This is a subject with many, many threads, I think you'll find one running only some lines down on this page in the engine section, the heading is '4 BBL. set up'. You should also learn to use the search function, and enter the words you look for. There are more than 103.000 posts in the engine section alone, so there is a great chance you'll find what you need. All red text are links that you can click on.

In general, the car's type and use, weight, transmission, rear axle and what you want to achieve, all of these and more factors are interconnected. If you post your car's vitals and your goals, there is a great chance you'll get the answers you seek.
