340 Street Build

I've seen it close enough to take the carbon off. lol

A dual pattern probably make more in most applications.


A cam say with .550 lift will spend more time in the cylinder heads peak cfms than a .500, do you need to though ?
Depends on where flow stalls. For a street engine, I’ll lift the valve to stall or slightly higher but not a lot.
I ain't sure I go along with the dual pattern thing. Usually with headers, the single pattern shines brighter.
Depends on the timing events of any cam installed.
