Stock stuff is good enough, especially for a motor that turns such low rpm.

If the module is bad than AC Delco should be fine and can be had at any number of parts stores. As far as wires before my 383 build up on my 85 I used the factory wires that you can again get at any parts store and you should be fine with both. The factory ignition system is more than adequate for daily driver and performance and if you have a stock vehicle than I see no reason to spend alot of money on these two parts.

I just put an Accel cap and rotor PN 8122 on my 84 and it is working great. I'm still wanting to upgrade to a Mallory or MSD distributor. Hope someone will have some goods idea's on that. I have Mallory 8mm wires.

Well, back in the day I had a SBC 355 with a HE cam 490 lift 280 dur. It was a strong runner. One day for no reason I switch out the HEI for a Mallory Comp 9000. That single switch made the most improvement in seat of the pants dyno by far.

The "seat of the pants" gain is generally proportional to, either the cost of, or the difficulty in the installation of, the item under consideration. Ignition upgrades(?), especially in mild (read as cylinder pressure) engines are notoriously money wasters. Often what is being replaced is defective, and that leads one to believe the speed part is doing more that the stock item could. Examples: Replacing a stock 1984 fuel pump with an '85, or a distributor like jfitevette's, with a Mallory, when a GOOD, stock part was more than up to the task.

Most ignition upgrades on a stock or even a modified engine are a waste of money IMO unless you're really cranking it, RPM-wise. That being said, from a durability standpoint, MSD wires are killer. They really hold up to heat well. I've had them on my car for over 30K miles with stock manifolds, uncoated mild steel headers (which really put off a lot of heat) and now with the stainless headers which run cooler. No problems, ever.

I'll put a plug in for the MSD Blaster coil.It has a higher voltage and thus hotter spark.No real performance gain but engine seems to run smoother with it.The price was good too.ICM tells when to spark and all do the same thing but a stronger coil is a good thing in my book.

the stock coil is capable of 35,000 volts, maximum, and the HP coil is capable of 50,000 volts, what have you gained if it only takes 10,000-12,000 volts to jump the gap? If your mild engine requires much more voltage to fore the plugs than that, you have other problems.
Yes, I fell for the MSD coil trip, too. Runs no differently than stock and now my tach goes haywire at WOT. Stock replacement on the way.

The stock L98 ignition in good working order with correct plugs is all that is needed. I've experienced that Accel wires are no better than OE and deteriorate faster than Delcos, Taylor wires are pretty good.

EDIT:
I am going to correct myself as my theory is unsound.If it takes 10kv to jump the gap of a plug no higher voltage can be obtained BUT....a higher voltage coil has a longer duration of spark which is more important in the scheme of things and accomplishes what I described above namely a more complete combustion.The heat ranges of plugs has to do with how much heat they dissipate not generate so I stand corrected on that too.Here is a link to fully explain this info
