Default Where is the hold down bolt?

So I've read the timing post and the applicable articles several times and decided to TRY and play with my timing. Where would the hold down bolt on a ProForm HEI distributor be? Is it the bolt that is in the manifold that looks like a PIA to get to? I have very little car knowledge, so go easy on me, you got to start somewhere.

It's at the bottom of the dist. holding a clamp against its base. The bolt screws into the block. Hard to miss.

Next question. How do I determine which is the number 1 spark plug wire? The wire that goes to the 1st spark plug on the drivers, closet to passenger?

No, furthest (up-front), driver's side.

As to getting at that bolt, invest $6-7.00 on this tool. It will save a lot of frustration.

Well I cant trace that wire back, but I think I got it. The plug on the passengers side, closet to passenger is wire number 8 so if i go one over(counter clockwise) on the distributor, that should be #1 right? Yes, this is rocket science for me.

Good diagrams Paul, but on an HEI, that's not where #1 is.

First thing, buy a chiltons repair manual or a factory assembly manual they will have tons of info on these type of things with plenty of diagrams that will help you tremendously!!!!!
find a friend that is a gear head to help you out and teach you some things. thats how i started working on cars back 25 yrs ago and can swap a motor in a day by myself now!! plus it always helps to have an extra hand or a set of eyes while working on cars!!

I would suggest your first manual to be the GM Service Manual for your year Vette.
