D100 + 440 + 727 + 3.91 = tire spinning. Oops!

PICK UPS HA
I've been testing the D100 project this week. Getting some bugs worked out. Take off slow and it is way too easy to spin tires. Hitting 2nd under light throttle barking tires. 3rd will hit hard and break loose with 1/2-3/4 throttle. Zero traction with this truck. I'm hoping the 3.23 w/sure-grip and new tires will help. But, hey it's fun and I'm not complaining. I took the wife for a ride last night and oops...sorry honey I didn't mean to bark the tires. She did grab the door when I stepped on it getting a smidgeon sideways going into 2nd. Of course I also got the... you're too old for that look. We know most of us don't outgrow that part of the kid in us. No more rides for her!
Pick ups have very little weight on the rear wheels ,long beds are worse than short beds ,as far as front to rear weight ratio. Add a little power and all of them will do that .
