<DIV>Crane Cams recommends the following method</DIV>

<DIV>Set the intake valve as the exhaust valve for that cylinder starts to
open</DIV>
<DIV>Set the exhaust when the intake valve is almost fully closed.</DIV>

<DIV dir=ltr>Why would they be? The lobes for #1 and #4 should be 180
degrees apart as should the lobes for #2 and #3.
<DIV>If they weren't you would have a very odd sounding and rough idle.</DIV>
<DIV>If you have ever listened to a air cooled VW motor, the source of their
funny sounding idle is they fire one cylinder (#3) a bit retarded so it runs
just a bit cooler as the oil cooler is right on top of the #3 cylinder.</DIV>
<DIV>But like I said, feel free to pull your valve cover and verify what I
said. This is the internet, for all you know, I am an 16 year old red head
stringing you along.</DIV>

word that came to mind at the time. I think you understand what I was after.
So, several degrees either side won’t matter is what you’re saying. I was
fairly certain that was true, however, aren’t the lobes of intake on 1 and out
on 8 slightly shifted on the cam? <U></U><U></U></SPAN></P>

<P class=MsoNormal>TDC and BDC refer to the position of the piston in the
bore, or in the firing stroke. Period. <U></U><U></U></P></DIV>
<DIV>
<P class=MsoNormal>Piston at the exact top of its stroke? The piston is
at TDC. At the exact bottom of its stroke? BDC. <U></U><U></U></P></DIV>
<DIV>
<P class=MsoNormal>#1 at the top of its stroke on compression? The
engine is at TDC. <U></U><U></U></P></DIV>
<DIV>
<P class=MsoNormal>What you are referring to is the valve being on the lobe or
the heel of the cam. <U></U><U></U></P></DIV>
<DIV>
<P class=MsoNormal>If you doubt that when #s valves 1 & 3 are on the top
of the lobe that valves 6 & 8 are fully on the heel feel free to rotate
the engine several degrees one way or the other and see if the gap gets bigger
(it won't) <U></U><U></U></P></DIV>
<DIV>
<P class=MsoNormal>This is because a camshaft is a circle (base circle) with a
bump on one side. Anywhere on the heel is going to give you the same
clearance. <U></U><U></U></P></DIV>
<DIV>
<P class=MsoNormal>There are even some engines that instruct you to put the
engine @ TDC #1 adjust half the valves then rotate the engine 360 degrees and
then adjust the other half. <U></U><U></U></P></DIV>

<P class=MsoNormal><SPAN style="COLOR: #1f497d">Regarding Rule of Nine, I
understand having 8 all the way up to set 1. But there is a significant
rotation between “real close to the top” in front of, and after TDC. This
can be seen with rotation the engine and seeing very little to no movement.
Also, if I am not mistaken 8 TDC is not perfectly in line with BDC of 1;
there is a bias. This means that when 8 is TDC, 1 is not absolutely BDC
ready for measurement. So the question is, how do you ensure, with all of
that slop, that you truly have BDC?</SPAN><U></U><U></U></P>
