I think they are the best trucks ever produced, but that's why we're all here right? I actually prefer the TBI stuff to the Vortec (5.7 Gen-1) stuff. In my opinion, TBI is like optimized carburetion where the Vortec GMT400s were early MPFI setups, and the kinks were still being worked out. For me, part of what makes the TBI great is how simple it is. ECM reads the O2s and does some timing control, but that's about it. I agree that distributor at the rear of the engine is a pain! I always hate trying to get a distributor wrench snuck down between all the **** on the intake. But I have grown to really love the TBI, as obscure as it is. I may be a little biased, my TBI 'Burb is running TPI heads and a Vortec roller cam now, and I really like that combo. Still not as good as a Gen 3 drivetrain though... My preferences are pretty strange; I prefer the look of nearly all other GMT800s over the Cateyes (all 99-02s and the 03+ GMCs). I actually find the cateye front-end to be quite ugly... just my 2 cents.</blockquote>
