problem with timing ?
i want to ask you about a timing
the car has l76 6.0

230/238 625/625 113 trickflow

the problem is timing
just 20 , the car can't go more than 20 ?
-it starts to Knock when go more than 20
-tr6 spark plugs
-95 octane
-aftermarket timing belt
I have to run 11 degrees in the 1600 to 2000 rpm band as airmass approaches .60 g
.
At full throttle I use 15 degrees spark advance... premium pump fuel here is 90 octane, when you can find it.
