Hey im looking into buying a 1st gen k5 that has been converted to fuel injection or has a swapped in fuel injected motor. I ideally want 6+in of lift and 37-38in tires, 14 bolt, d60 front. Was seeing what everyone with good fuel injection was getting for gas milage. Also curious about TBI milage also. I have a 98 silverado with 5.7 vortec and only get about 15. Thanks.
