4.8 to 6.0

[zebra]

OP has a 4l60e not a NV. OP should look into a 4l80e. Trucks, lots of power, and the 60e usually dont mix well. read this.

yeah, i know... we just got a little off-track.

What do you mean power band? A 80e behind a 6.0 is standard. The factory sends them out that way. Sometimes they put them behind the 4.8. Besides. Most people that post times after a 60e-80e swap report better et's. Oh and you should knock on wood. Last few people that were talking about how their 60e's were still strong broke them shortly after. lol

wait - what came with a 4.8/80e?
