65 Corvette Spark Plugs

[Popzak]

I have a 327/365HP Stingray.I would like some opinions on which is the best plug to use.It was fitted with AC44 at Factory.I have AC43 in engine now.I was told NGK are better.

Thank You Eddie Zak

Hi , I wouldn't worry too much ,the ac`s should be pretty reliable .

I have a blower on an LS6 and use NGK tr6 plugs only cos that's what came with the kit.

I would use whatever is easier to get , if you go non ac just make sure they are in the correct heat range .

Cheers mate.
