Re: NGK Spark Plugs..
Rob, I agree with this...after doing the BB car I wanted to put some new plugs in the 69 granny 6 cylinder. They didn't have the NGK's for that motor..so I installed a new set of AC Delco's. It still has a slight roughness to the idle...I plan to find some NGK's and try them for comparison. We have them in several of the 70 L78 cars and they work great.
