New member first post. I am looking at a new engine. LS swap is a very simple swap for me to do. My concerns is fuel economy. Most guys don't care but my commute is roughly 100 miles a day. What numbers are you getting at the pumps? I'd really like to run a 4.8 w the 4l60 for the cheapest scenario.
So 4.3 vs 4.8......
Truck is a 96 RCSB w a siezed 4.3
Pockets aren't deep. Was also considering a 4.3 mated w a 6L80E hell even a 6L90E and put together a stand alone for that. But it would be one or the other couldn't afford both. Any input? Or any idea on mpg City/Hwy.
