Thanks guys ,looking for the answer for the 4 mill cub clean up port on alky......gonna fire it tommorrow and dont wanna fuck it up ..haha..JB

 

6 to 7 degrees advanced is a good starting point....I know of people running cubs on +10-12 degrees...with good success. Let your plugs be your guide.

He runs more than that...12 (plate maxed)...

 

A lot of different factors...7 is a great starting point. I always ran my 10 mil at 9. I bumped it to 11 at the strip, kept the same ET but lost a few MPH...when I get time, I'm going back to 9...:)
