I am not sure where to set the igntion timing.
 

I have never adjusted the timing on a 911 engine before. I have a 1976 911S that I took the 2.7 out of and put in a 3.2 with Weber 40Ida 3cs and Msd and Pertronix Igntion. I am not sure where to set the timing. I also don't know where to hook up my timing light. Do I hook it up to the #1 cilinder and + and - on the battery. I am not sure. Any help would be great. Thanks.

I don't know how your distributor is set-up as the 3.2 distributor didn't have any points or magnetic pick-up. Assuming you have some trigger inside the distributor I'd try to get 25 degrees of advance at 6000 RPM and see what you have at idle. Initially you could set to TDC at idle and then spin it up to 6000 RPM and see what you get. Adjust from there to get your advance to 25 degrees at 6000 RPM. 25 degrees should be very safe but you could try using as much as 30 degrees to get max power. Go up a little at a time and listen for knocking.

Timing light hooks up like you guessed.

I don't think you can even adjust the 3.2 distributor. I bet the engine has the 76 dissy in there as the timing comes frome the flywheel rotor and prosessed thru the motronic unit. That wouldn't be fun to hook up in a '76.
Oh pertronix ignition, yeah, it's the old timing system. Just do what Eagledriver says. There should not be any vacuum line as you have carbs and it's all mechanical. the fun is you can play with it with your hand!! Err, till it runs great.

There is +12V in the engine compartment. On my SC I usually found it at the fuse block on the driver's side. Then hook the negative lead to ground, any unpainted piece of hardware on the chassis will do.

The plug wire lead goes on #1 cylinder and off you go. Shine the light at the crank wheel and look for the timing marks. There is a Z mark for 0 degrees and there should be another one for 5 degrees advance.

Report back if you can do this successfully and I am sure others will chime in with more numbers to aim for. Be careful around the engine - no loose clothing or getting close to the fan / belts. You would not be the first to lose a finger or two in there.

I have a timing light that lets you retard the strobe, so you can dial in / read to the degree without having any timing marks (aside from zero) on the wheel. If you haven't bought yours, I recommend such a model, i.e. from craftsman.
