That would be exactly right.


I'd be running 1 light blue and one light silver with a 3100 lb car and that gear. Or even 2 light silvers.... and get all the timing in by 2500 rpms...

Did you READ the plugs and find "salt and pepper" on the nose?? Also do you know how to read the strap -- and see where it changes color? Perfect timing will have it change color right in the apex of the bend.
