You can't go wrong with a Sterling. And actually, the cost is less than half that of a Racing Beat Holley carb setup. The Sterling carbs are stripped of all the BS that you don't need. Go to www.sterlingmetalworks.com and take a look at one. It is a great way to simplify your engine bay too (I only have two vacuum lines, including the one to the brake booster). If you want an idea of how they perform, just check out my videos. I've never lost a race due to lack of horsepower.

Airflow is my life
nice catch. That sucker will probably outflow any Mazda 12A stock manifold. Everytime they added emissions crap to them they ended up restricting flow. Id keep that as a good base for your project.
