Timing for a 318 in a 78 Aspen

Does anybody know how many degrees off from TDC I should adjust to when timing the 318 motor in my '78 Aspen R/T?

***If it makes a difference- I have a mechanical distributor that is not original equipment.

If it's stock I'd start about 10° before TDC, if it has a performance cam it could be up to 20°.

I have a new set of points sitting around, so I figure I might as well put 'em in and change the condenser while I'm at it. Any idea what kind of gap I should have on them? Also, what kind of dwell reading should I get when it's all said and done? The motor is a 318 with a mechanical ignition system.

You have a 78 Aspen with points???
Why???
It should have an electronic ignition.

As far as timing, modifications and age factor in. While 10* is a std advance, your ear or a tach/vac gauge gets the final vote.

The first owner of the car was a complete idiot. He removed the electronic ignition and lean burn system and put in a mechanical ignition. I could install an electronic system for ~$250, but I can simply maintain the mechanical one for ~$25. My wallet likes the second option better.

The points are just simpler to install when replacing a leanburns twenty five wires.

Understood, but the electronic ignition is basically a fire and forget.
Most of the kits I've seen were into $150-$190 range.

Not having to play with points, dwell, etc is worth the price of admission, for me anyway.
Just a thought.

I agree I would put a conversion kit in it also.

Iowan,

What do you think of this kit from pertronix (https://pertronixbrands.com/products...31797276409892) paired with one of their "flame thrower III" coils?

Just get the Mopar kit or one of the knock-offs from Summit or JEGS.

You can put the stock reluctor and pick up on the mechanical points plate. That exactly how we upgraded in the late 70's. Then just buy the matching electronic control unit and hook up four wires. I don't know why anyone buy's a "kit".
