Alright guys...here is the deal. I have a 2003 Silverado 1/2 4wd ex cab with the 5.3 gasser in it. i have almost 200k on it and have been thinking about upgrading to the 6.0 gas motor(bolt-in). The other night I got a wild idea and said, "What about a 4bt?" What do you guys think. I am in the process of dropping in a 14b SF rearend already. I would put the 3500 torsion bars in for the extra weight and I should be set to go. I tow 6000# with truck on occasion and drive ALOT. The mileage would be much better with the 4bt and the longevity, etc. But, what problems am i going to have with the guage cluster and the computer issues? Any help would be apprecited. Also-should I keep the built up 4L60e or go to 4L80e or manual? I know this has been long but I am appreciative of your help. Thanks in advance!
