The #1 plug is on the driver's side front of engine. 1977 had more than one 350 engine, L48, L82 and California. You dont have the emissions decal near the drivers side hood lock? You dont have the owners manual?

It is not my car and I am no where near the car to look.
I know the car was originally bought in WI and the engine was just replaced with a 300hp GM longblock in the past few years.

You want to set the timing up for 36 degrees total, exactly like a Ford. If you don't know how to set total timing, drop me an e-mail request for my "How to Set Timing" paper, and I'll send you complete instructions.
Here's me and Matt King, former Editor of Hot Rod Magazine, setting up 36 degrees total timing on a 302 Ford at the Westech Performance dyno facility for an article we did for Hot Rod:

If you set the timing to 10 degrees at idle, you'll probably pass an emissions test with no problem. But a Honda Civic is going to blow your doors off. You really need to set the timing to 36 total and disregard the initial.

A dail back timing light is the easiest way, but depending on the diameter of your harmonic balancer, you can put another mark on it for the 36 degrees. Take Lars up on his offer, as he'll take care of you.

Sure you can. Measure the circumference of your harmonic balancer, divide that number by 10, and put a mark on your balancer that distance clockwise from your existing "0" line. Complete instructions in the paper I suggested to you.

OK, now, I don't want to ruin the party, but you also need to modify how quickly the centrifugal advance comes in. A stock distributor can still be advancing past 5000rpm. You need it to be all done advancing at 2500-3000 rpm, and for that full advance to be at 36 degrees. Just follow Lars' paper, and you will be fine, that's what I did the first time I recurved a distributor, and it's easier than it looks.
I have a plain old timing light, too, what I did was get a tape that sticks to the harmonic dampener, and shows the degrees. You can get 'em from Jeg's or Summit, or just make a mark. Good luck!
Keep the shiny side up!
