So do you have it put together and running it with this cam and 4.10 gear combo right now and it works well, or this is yet to be tested?
In general you have more flexibility with rear gears in a stick car because you control the motor rpm at gear changes, but I really don't believe there is a perfect max performance, good fuel economy to be had. It's always a compromise, but for me at this point in life I question how many miles a year that I'm actually going to drive it. It's not like I'm commuting to work every day on the freeway in my hobby car, so I lean toward the bigger performance gears and enjoy the car more.
