How can you supe up a Chevy 350 5.7?

Answer 1

There are a number of factors that dictate the answer to your question. But, the most important would be your local smog laws. If these are a factor, then a conservative approach would be needed here. First off, the factory exhaust sytems leave a lot to be desired. And, biggfer, and better, will not defeat your smog abligations. Remember that some back pressure is needed, however, a good 2, or 2.5 inch exhaust sytem, with a coup[le of high flow cats., and flowmasters, would really open up the breathing. K&N makes a high flow air filter, that pays off, as well. If you want to go further, they offer cold air systems, as well. Both of these mods are 50 state legal, and will spice things up for you. If smog is not an issue, follow these moves up with work to the induction system, carb, or injection, then more cam, and some bigger heads. Engines are just air pumps. The more you put through them, the more power they give.
