Anyone test drove the new ford 7.3 gas or the chevy 6.6 gas ?
2.2 MPG. That trailer better be full of gas!
The new DI 6.6 GM gas motor is a little puzzling, but maybe not given its intended purpose. The GM 6.6 gas motor has 20 less HP than their 6.2 and the same torque. They have the same bore size but obviously the 6.6 has a little longer stroke. The 6.6 is a iron block with aluminium heads versus aluminium block and heads for their 6.2. Compression on the 6.6 is also lower than that of the 6.2.It seems GM designed the 6.6 gas motor more for heavy working and longevity but I'm a little surprised they didn't build more power into them. Only time will tell, but I think the new Ford 7.3 gas motor will be the stronger choice.
