Understanding Cylinder Head Porting and Selecting a Camshaft to Match

For some people cylinder head porting is witchcraft – but in today’s world of information at our fingertips we can demystify the witchcraft. While we're on the topic of magic let's take a look at how cylinder head flow and camshaft selection can play hand-in-hand. First let’s look at what porting actually does for your engine. We’ve all heard that an engine is an air pump – so air in, air out. Our goal is to increase the airflow of each runner measured in CFM. Most people will look at the peak CFM but they’re missing the majority of the picture. Remember, the peak of your lift isn’t your entire lift. Porting your cylinder heads typically means increasing the port size of the intake runner diameter, while the act of polishing is meant to remove imperfections in the runner walls and floor. Performing a simple port and polish will help the air to move in and end of the engine efficiently. Here we are using a Pontiac 400 set up with a 6x-4 heads, Edelbrock RPM, and a Summit 2802. ______________________________________________________________ 🏁Check Out Our Website! https://www.lsxhunter.com 🌎Playlists: 1967 LeMans -    • 1967 Pontiac LeMans   1965 GTO -    • 1965 Pontiac GTO Restoration   1978 Firebird -    • 1978 Pontiac Firebird Formula   👚LSxHunter Apparel - https://lsxhunter.com 🙋‍♂️Join Us on FaceBook: Facebook:   / lsxhunter   Group:   / lsxhunter   🛒Working On Rust Buckets?
