It wasnt right if it's always been missing. Or am I confusing what you're saying?
You had a set of too weak springs. It didn't rev, but didnt break up? Or the weaker springs pulled clean to 6K? Did it ever pull cleanly tp 6K?
its never missed untill i installed the 4.88 gears...
it always was able to pull 6 grand with no issues, until the gear change, before that, never missed, never broke up
since the gear change from 3.91's to the 88's it always breaks up above 5800, no matter jetting,timing, exhaust setup, air cleaner on or off, slicks or street treads
i havn't changed shift points, fuel mixture (100oct leaded), anything else... just a gear change...
