Camshaft timing when the sprockets are ONE tooth off from straight up.

Isn't that kind of slow for a 1/8 mile race?

:lol:

A 9.30 1/8th would be a mid 14 second pass in the 1/4

screws have the thread cut/rolled right up to the head, bolts have an unthreaded section between the head and the thread. so they are head 'bolts'. you never see them fully threaded as that would cost the factory more money/time.

THAT is an excellent explanation.
Ehrenberg also uses the term "Cap Screws".
Maybe he is just being facetious there?

You could distinguish screws from bolts...
screws: internally driven
bolts: externally driven

During my machinist apprenticeship, we were taught that what makes up a bolt are two nuts that are threaded onto each end of a stud and a cap screw is a screw with a fixed head on one end and they can have full threads or partial threads....like a head bolt for example. The automotive field calls things differently.
