shakesvho Posted February 12, 2009 Report Share Posted February 12, 2009 (edited) 4l80 is the way to go, did you get your 80 build or is it stock Edited February 12, 2009 by shakesvho (see edit history) Quote Link to comment Share on other sites More sharing options...
zippy Posted February 13, 2009 Report Share Posted February 13, 2009 well i had the tune done before i had the tranny rebuilt and i forgot about parmeters on the tune my fault but i payed more money and this time and went ahead with the 4l80 The 4L80E is quite an expensive conversion. I'm assuming you plan to make big power to make it worth it. There are quite a few 11 second trucks out there with the 60/65/70E's. With correct tuning and a properly built trans you should be fine without doing the conversion. Quote Link to comment Share on other sites More sharing options...
