Hey - I am currently running a set of Autolite AP26 spark plugs in my 1970 350 and they are due for a change. I think the stock AC Delco plug is the R45TS. Here is my question: Can I run a set of AC Delco R44TS plugs without any problems? I have a set just sitting around and was curious if I could use them. Thanks, Ken Krisher
