Hey gang I was talking to someone who was carburetor tuning their 6 cylinder and with those long intake runners discussing how it can sometimes be difficult to achieve uniform fuel mixtures, one particular cylinder will typically always be leanest.

I got to wondering is there an equivalent thing going on with the Y-Block due to its intake design? I ordinarily check #5 spark plug for a quick check as access is easiest but too lean is something to look carefully for, along with preignition, or spark knock. Seems like the way the center runners are stacked it might be different, but I dunno? Is there a particular cylinder to watch?
