Old post but had to reply. I've had a Fitech on my 72 GMC since 2016 and have been to San Diego, and AZ to spend the winter there with the truck. AZ is 2500 miles one way and SD is even further. That was 2017 and 2019. 2018 we took it to FL for the winter (shorter drive at 1400 miles) and last month again to FL for a month(that was 4300 in 3 1/2 weeks). We've gone east for 2 weeks last summer(2300 miles) and may do it again. Same 400hp Fitech. Add in all the regular driving plus the driving while down south and we are over 50,000 miles. This is on a 5.3 with a carb manifold. Way better mpg than the original 350 and I run 3:73 gears. Even the original paint is holding up.
