Well, it's an extreme case, but it's a very large motor. A 535 has a lot of swept area, so it's possible that a strong downward stroke with the exhaust valve open could create a decent amount of exhaust vacuum.
During cranking, if cylinder 1 fires while cylinder 5 exhaust is open, you could get a strong toke on the #5 primary tube. If a set of headers made me tear a motor down twice, that would be one former set of headers!

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
