If you go to Autozone's website I just went thru their automated search and it spit out 10-12 choices. However to qualify that they still list the R43 as the recommended AC Delco plug they also list the R45S.

It's somewhere to start though... Dave

I list Raleigh as where I live because most would never know where Clayton is. I live just outside of Raleigh so the next time you are in town come by and have a beer. Make sure you come during the summer on the 3rd Saturday and we can cruise up to Grill 57 where we usually have about 200 plus cars...

I ran the R45S AC Delco plugs in my 327/350 motor for about 4 years with no problems. The motor was for the most part stock during that time and many others are running these same plugs with no problems. I have had to change plugs now but that is related to the AFR 195 heads that I'm running on the motor currently.

Since the AC 44 & 45 plugs aren't avalible , just the resistor plugs, I use NGK B4 (stock # 3210). It is a non resistor plug with the heat range very close to a AC45. I use them in my 56 210HP and my 64 300HP.
