Gas Mileage
I just got as 56 F100. I am going to make it into a daily driver. The 272 is in need of a rebuild. I may change out the engine instead of doing the rebuild.
Can any of you tell me what kind of mileage differences there is between a 351W and a GM 350. Consider the same setup on the rear end and either a C6 behind the Ford or a 400turbo behind the GM. I am looking for around 300HP from the setup.
