Best Fuel Option

Dam,you have a hot little 318.
Ditch the dual snorkel for a open element with a K&N
Put in 92 octane and bump up the timing to 35 total.
And light em up !!!!!!!
Now we arte talking !!!!!!!!!

Unless you are daily driving and looking for MPG's.
Then run 87 with your 10 advance.If it isnt pinging you are fine.
