So now have a thousand miles on the new motor. Checking the plugs noticed that the 4 and 3 plugs are a lean. Dose this seem right. Have a Holley intake. The back plugs seem to be rich. Some guys say If it crank's and runs don't worry about it.

I sort of agree with that. I have drove myself crazy trying to figure out what my plugs are telling me. And unless there is and noticeable issue, Drive the Hell out it!!!!!! Old Picture of the RR Before restoring

Thanks for the info. Going to call Holley and see if there is a divider plate to put under the carb or something. It is a midrise intake. :thumbsup2:
