Butterfly Valve Modification


Recommended Posts

Posted

My truck is an 07 Classic with the 4.3L engine. I have encountered information on another truck site regarding the modification of the butterfly valve of the 4.3L throttle body. The mod is to cut off the curved lip that is on the bottom of the blade. It is supposed to give more power and better mileage with the lip removed.

I can see where there would be more power because of more air entering the system. I'm not sure if mileage would improve.

Does anyone have any experience with this and what were the resullts?

Never heard about that mod, if you want more airflow, upgrade the throttle body or better yet, both TB and Intake manifold.

I've searched all for an intake manifold and have subsequently found a company that makes one for my 4.3L engine. Any ideas on where I can start looking for what/how to do to upgrade the TB?
