Default My experience

I have noticed only a very slight drop in MPG following my 410 install. I base this on hwy driving in 6th gear at 75-80 mpg only. When off hwy I am normally not a slow driver (but, of course, obey the speed limits).

Stock cam - it is a bolt on car.

Mileage around town is better because I am not wailing on it yet. It is posted to demonstrate that good mileage can be had when you are driving the car normally with 4.10s. I lost appx 1 mpg on the highway.

Really? I never would have guessed............ Yes, I am aware but I was expecting a larger dropoff in mpg.

I said - if you drive "normally" meaning not with your right foot fully extended to the carpet. Thanks for being a "Master of the Obvious". Please - tell me when I can expect the moon to reappear.
