Why does my 351W engine have flow restriction?
Why does my 351W engine have flow restriction?
Exhaust is a common place for flow restriction. Upgrading to high-flow exhaust headers can build significant horsepower, as long as they’re matched to the flow of the rest of your engine. Once you’ve removed flow-restriction from either side of your heads (exhaust and intake), the heads themselves need to be “flowed.”
