I believe your rental was a 3500 (1 ton). That explains the 80 psi (and some of the wonderful ride quality).Bob wrote:Highs: Had 5 miles on it when I picked it up, good powertrain, transmission rev matches downshifts well in manual mode. The satisfaction that comes with parking it in a normal spot. No need to pack efficiently.
Lows: Vintage 90s GM build quality (bad panel gaps, interior squeaks). Horrible driving experience. Rides like a HD pickup from 20 years ago. Steering wanders a lot. 14.8 MPG over 700 miles of mostly highway.
Also they apparently got rid of the 4L80E so yours had the 6L90, which was also used in the CTS-V2 (and also HD pickups).
I wonder if we are in a valley of cheap LS stuff, because they will be switching everything over to the Gen Vs and fancy transmissions. So maybe now is the time for a junkyard LS build w/ 4L80E.
Yes, I look at that van as an LS donor. You broke it in right, and someday when it has 300,000 miles, it will get ripped out and put into something else, have 12 psi stuffed into it, and make 650 rwhp.
