How much does a Chevy 350 weigh

Keep in mind that many of the upgrades to the Chevy 350 have the potential to break local laws regarding emissions or noise. Check your local regulations before making any modifications to your Chevy 350.

Exhaust Header

Installing larger headers on a stock Chevy 350 engine can increase the torque by 53 foot-pounds and add 16 horsepower. The headers are the weakness of the stock design of the original Chevy 350. Thus, modifying it should be the first thing that you’d do.

Think about it this way, to increase the horsepower of your Chevy 350, you need to increase combustion. Once you increase combustion, your engine will produce more exhaust gases. Thus, you need to have a large enough exhaust system to handle all the exhaust gases that your engine would generate after producing more horsepower.

Turbochargers Or Superchargers

Either one of these two will push more air into the combustion chamber. If done properly, you can expect an increase of six to eight percent to the horsepower output per pound of boost on your Chevy 350.

A Chevy 350 with cast iron pistons can handle up to seven pounds per square inch. This can result in an almost 50% increase in the total horsepower output of your 350.

Installing Forged Pistons

Replacing your stock pistons with forged pistons will allow your Chevy 350 to handle even more power. Forged pistons have more strength than the stock pistons in your Chevy 350.

These pistons are preferred by car enthusiasts because they are more durable than stock pistons, and they can easily be customized to many different configurations.

Improving The Air Intake

Replace the stock air intake system with a cold air intake system. Cold air is naturally compressed because molecules move closer to each other at low temperatures. Naturally, compressed air has more oxygen than uncompressed air. More oxygen in the combustion chamber means more horsepower is generated by your engine per revolution.

Most cold air intake kits include a heat shield to prevent the warm air coming from the surface of your Chevy 350 engine from mixing with the cold air going into the air intake.
