Modified engine crewcab gas mileage?
The truck is a 383 stroker small block not big block. With the lockup converter the truck should sit around 2400ish while going 65 if I end up doing 35s, which I honestly don't think is that bad, My 88 Blazer with a 700r4 cruises 70 around 2k on a flat road, even higher if going slightly uphill...- Nick88
