351 install questions
Hi all, did the req searches but looking for a definitive answer to these questions...
1) I see some people remove and block off (with a bolt) the vacuum switch thingy just on front of the cylinder. Is this required, needed, or beneficial in any way?
2) when cams are removed, does the timing chain have to be kept taunt, or will letting it go slack (not dropping it in of course) make it come off whatever it is on down in the deep?
Thanks!

2 - The came chain doesn't need to be kept taught and it would be difficult to do so. If you do drop it, it's not that big of deal. Either fish it out or pull the cover, which I maintain isn't a bad thing because you'll get to inspect and clean your oil pickup screen. See pics in my 351 build thread.

1 - Not required. The primary benefits are cooler exhaust and pipes, and getting that smog equipment out of the way.

Question on the timing, if I mark chain and put it back exactly where is was originally, is that good enough, so do I have to readjust timing?

The chain position does not change the timing, the locational position of the cam is the timing. It is better to put the crank at TDC then remove the head. Then put the crank back to TDC and reinstall the head.

Take your time, make the work area very neat and clean. Bring in as much lightnings as you can. 1 minute cleaning before yields two minutes less build time. Get all the tools you'll need together in one place.
There are many excellent build threads here, as referenced above. Read through those.
Put the wrist pin in the freezer the day before you start the build. This will shrink it somewhat making it easier to install. You can also make a simple wrist pin install tool with a bolt and some big washers.
Preparation is really important.

Thanks al! Got it mostly done before I had to quit to feed the kids
So with the block off plate on, obviously eliminates the one hose... Can the rest of the smog crap just be removed, or are there other things that have to be plugged/cut/etc
