If you have the stock heads on your 5.O, stick some Autolite 23's in there gapped around 030ish. Autlite 26's are absolutely the _Wrong_ plug for your application!

If you have a tappered seat designed head (stock, GT40 irons, etc), the NGK TR6's work great gapped at .035. If aluminum, NGK makes another line that are basically the same but with a flat seat.
Whatever you decide, you'll want to get 2 ranges COLDER than stock, gap 'em at .035...& DON'T run a platinum plug.

You will want to run autolite 3923's gapped at .030 to .035 with those "elderbroke" performer heads ![[burnout]](graemlins/burnout.gif)
