Just wondering what highway mileage you guys with stock LS swaps were getting.Thinking of putting a 5.3/4l60e into my 3.54 geared '67 c20 if mileage increase would be around 18 highway or better.Currently have 327/TH400 and trying to decide if a 700r4 behind my 327 or go to modern LS setup.Currently have a 2002 Silverado with 4.3,gets 20MPG in highway.If I can get close to that mileage, I would rather drive my '67.
Thanks,Gerald. |
