New Gears.... now what???
I posted another thread on swapping my 3.23 gears for 4.10 on my RWD 2005 GMC Sierra 1500 with the 5.3L and 4 speed auto (4L60e). I took the truck in this morning and picked it up about 2 hours ago...

Are the new ones using variable valve timing ? That's amazing stuff. On the best ones they tie it to the computer. Horsepower numbers are meaningless for towing, torque on the other hand. With your 4.10s, you may wish to look at your torque versus rpm curve. When my son built a 4x4 engine, he and the camshaft grinder optimized it for torque, low end partially.
It takes torque to make more HP so they go hand in hand. More than likely, I'll do a custom tune with a local guy that's well known for tuning a lot of weekend racers. I'll speak to him face to face before I commit to be sure he's tuning to my towing needs and not just for performance. A cam is always another option. ;)
