The results from the poll show that most of you felt there were too many forums. The most popular choice, by far, was to consolidate them into chassis type, so that's what I've done.

Please let me know if you find any problems or I missed anything.

Thanks to Eric, for giving me a little kick and getting me started on the conversion.

I'm currently using Delco Rapid Fires #8. Car is basicly stock. Has BBK H-pipe with FloPro mufflers and stock 21/4 tail pipes, larger MAF and sample tube, K&N filter, 9mm plug wires, and timing bumped to 14.

What are some other suggestions for plugs? I've been pretty satisfied with the Delcos.

Also, anyone have any tricks/tips for swaping out the hard to get to right rear plug.

Thanks
Jim

Your 5.0 will run best with plain old Autolite (or Motorcraft), or NGK copper plugs. At least, that's my experience. The upside is that they're quite cheap (Autolite is 96 cents per plug at WalMart). The downside is that they need regular replacement, unlike a Platinum plug.

Also, you can play with the gap. Stock gap is huge (54 thousandths, if I remember). If you're running the stock ignition/plugs with a blower, you'll need to get a colder plug, and/or gap down to 32-35 thousandths to keep the spark from being 'blown out' at high rpm/boost levels. If you're running a mildly modded engine you may want to change gap to something like 45 thousandths on a stock type plug.

The larger the gap, the higher the voltage required to jump the gap, and so there's more energy dissipated in every spark - lights off more cleanly (lower emissions) and you get better torque at low RPM. However, the larger the gap, the harder it is for the stock system to fire the plug at high RPM.

Anyway, I like 0.045 gap on Autolight plugs with 14 degrees timing on my '94.

Best regards,

Oh - right rear plug (faces toward the firewall).

Two options:
(1) Use NO ratchet or extension on the plug socket. Most plug sockets have a small hex section nearest the ratchet hole where you can put a large wrench.
(2) With the hood up, use a BUNCH of extensions, AND probably a swivel nearest the socket. Extensions go between the lower edge of the opened hood, and you turn the ratchet from out by the windshield (!)

Best regards,
