Plug Type/Heat Range - AMC360

[rollbar]

I have an old book for the 258 and it does have some 304 specs.

Book reads N-12Y as a plug type.

Question, what plugs are you running on a stock application (if that means anything anymore :) .

All I have is a Accell coil and the standard cap/rotor and 7mm wires.

The cap/coil are new, w/the accell coil, should I open the gap more or keep it @ 0.035 as it reads for the 304cid.








Thanks again,
Jim
