Chaging plug wires and plugs tommorrow, wondering what plugs I should get and at which gap. Car is modified, with items in my sig.

Thanks in advance,
J.

autolite 25s(I'm pretty sure it's the 25) seem to be favored around here. .054-.056. correct me if I'm wrong..

Yup - run as big a gap as you can without compromising spark reliability; stock is in the .050-.054" range.
