I was curious to know what kind of track time you guys are running in your swapped OBS trucks? Stock 5.3 or 6.0L times would be great.
I have a 6.0L/4L80E in a 1990 RCSB and was curious as to what I could expect from it.
The truck is pretty much stock except for a k&n filter and some flowmaster mufflers.
I even still have to stock gears (3.08???) I am not sure what came stock in thses trucks, and no posi.
