Timing was set according to the valve cover sticker. It corresponded to the calibration code found on a tag attached to ignition coil. You may have to fudge the timing to get it right, but I think 10 degrees BTDC is a good starting point for that engine.

Yeah. If gutless, advance a couple degrees and drive. If you get ping, back off a little. You don't want any ping when you accelerate. Heavy loads may make that advance setting worse.

Advancing is to turn distributor body clockwise, in case you were wondering.

I think on the 79 400 they came out retarded about 4 degrees.

All the info you require about this is on one of my web pages.

I'm really suprised Mark didn't say anything about that

Calibration code
8-62T-R0

The tune up Specs are in 2 nd section of page.
look at info corresponding to the calibration code.

I'll look it up for you in my NEW emissions book

I didn't need to: I knew Dennis would be here with links and everything!
My evil plan worked!
