65 327 plugs?

[FireFly]

I was going to go pick up a new set of R43 plugs for my 65 327 this afternoon but read on the thread below about stepping up in heat range to R44. Should I do this or stick with the R43's?

Also, what is the suggested gap for either the R43 or R44's?

Thanks in advance!!!

FireFly,

Unless you spend a lot of time at high at high RPM on the track pr cruising on the highway R43's will look like this:

I recommend stepping up to R45 - same car and they looked like this:

Almost forgot - I'm pretty sure the gap is .035

no track time and limited hy time and YUP- those look like mine!! I'll try the 45's- any suggestion on gap?

btw- Thanks for the quick response. Heading out the door in a bit to pick up the plugs and a new delco oil filter.

Sorry about the last post- did not notice you had listed the gap at the bottom. Thanks again!!

allcoupeup has it correct and right on point. The R43 is TOO cold.

Just changed the oil and put in fresh R45's- man is she running great now!!! There was a lot of junk built up on the R43's.

Thanks again for the great info!
