Re: NGK spark plugs..
Tom, I run the UR5 in my motor in the Nova, 70 L78 Motor. Thats the correct plug for that motor. They are great!! Really woke the combustion chamber up.. I was using the new AC Delcos and they were junk. I was getting a surge in the RPM range at about 3,500. I put the NGK plugs in and it made a huge difference, much smoother at idle and strong the through RPM range.. I highly recommend them!! You can pick them up at Advanced Auto Parts. Thats were I got mine last summer. I think they were like .95 cents a plug.. Well worth it!!
