I have my plugs gaped at .045 right now and wanted to know if the gap is good or should I go to .040. Just wanted to see what everyone is running theres at and have had good luck with. Thanks.

With the cam in it it is a little rough at idle. But I have put about 1800 miles on it, since the cam has gone in and several sprayed passes.


Edit. The cam has been in it since the first week of May. The plugs has been it since last year.
