Many here have changed T140 intake timing...Stock timing for most is 92 to 94 degrees intake lobe center.There are some with 106 degrees....the early timing kills off the top end and increases the possibility of detonation. The later timing costs power on low and midrange rpm. As said aove, about 100 degrees intake lobe center makes the best overall power for road use

But a V8 engine is a good start for me
Think I'll drive to find a place, to be surly"
