Spark plugs for 1700 Super Sprint?

[pethier]

My 1700 Super Sprint came to me with NGK B8EC S spark plugs.  It seems to run well.

 

Should I stay with these, or is there a reason I should use different plugs?

 

Torque is probably not critical in an iron head, but what should I shoot for?

 

What spark-plug gap should I use?

 

The car is used for autocross and pleasure drives.  Long trips to distant places is done in a trailer.

I run NGK BCP6ES in both 1600's   In my Westfield and a formula ford

they come gapped about .030 and that seems fine

20-25 lbs torque

 

I forget how NGK runs their temp scale

if the B8 is colder, and you have higher than stock compression, I'd think it was OK too

A search locally turns up BCPR6ES.  which MAY be the same thing in a "resister" plug.  Is this OK?

I think you are right on the "R", but since you have no radio...

Shipping is always the problem with me.

 

I have tracked down some  BCP6ES to be delivered to 2 local NAPA stores.
