I would change the gearing to 4:56 in the rear and front. There is a way to change the tranny shift points to make it shift better but you only have 6 times to change it then the PCM stays at that constant. I wouldnt go that route since I changed mine and still wasnt happy and I have a 351 with 3:55 gears. I used to turn overdrive off everytime I drove it and it did help but I got tired of screwing around and just changed gears to 4:56 and everythings good now and changed my constant on the PCM back to original. Your tranny will thankyou!!!
The 4:56 gear makes sinse cause I used the gear ratio formula and came up with 4:10
To make it about stock. Why do stock when you can get a little more with 4:56 's. Thanks for the info
That's what I have been looking for

How is your truck on the highway about 65 is it pretty freindly. How is the gas millage.
