Re: Re-Installing Rocker Arms
Thanks everyone. I will take all of you up on your suggestions. I also just replaced the timing chain so I have a lot of things going on. I was avoiding taking it out of TDC until I get the timing cover back on. I had the timing cover off as I wanted to make sure that I was on the compression stroke at TDC, and my understanding is that the only way to tell this is based on the position of the rocker arms. (Although right now they all look like they are in the same position except for the one) Logically, I was going to install the rocker arms see if I was on the compression stroke at TDC and then finalize the timing cover install. Does this make sense? Any suggestions on this? Should I juts lock up the timing cover or do you think I should run some tests prior to this?

Re: Re-Installing Rocker Arms
Woah now, back up a step or 3....
You can't just 'guess' at a timing chain install!
The gears have to be lined up correctly with a certain number of chain
links between the dots on the gear wheels.
Trying to rely on the valves being closed on #1 just plain will not
work.
You need to take a straight edge and hold it across the centers of the
crank and cam shaft bolts. You then line up the dots on the gear wheels
close to each other and in line with the straight edge.
Once the gear and chain set is on lined up this way, you turn them until
the dot on the top big gear comes around to 1:00 position. You then
count the links between that dot and the dot on the small gear. You
must have 15 link pins between the dots.
I usually set them up on the bench and then carefully put the whole
works on at once.
This is for a 258 block.

Re: Re-Installing Rocker Arms
Hi Doug,
I didn't understand you question, it may have to do with knowing
where top dead center, compression is, which is when the timing marks
are in align as pictured: http://www.----------.com/sprocket.jpg
