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.
I'm running 3.42:1 gears, 4l60e/vette servos, and 4.8L with LTs, CAI, 1.75:1 rockers, and hypercrap 93 octane tune with trans pressure boosted. I don't think there is much of a weight difference between the OBS RCSB truck and my 2002.
I ran a 15.3 lately without the tune or the rockers. No telling what i run nowadays. I also have terrible reaction times, like .4s is the fastest i've gotten
What's ricky run? That's probably the closest combo, most of the OBS swaps on this site aren't screwing around.
12.1 all motor, also your reaction time has nothing to do with your 1/4 mile time.Quote:
