I hope the 6l90 will fit. I was going to put in my chevelle but I can't cut my tunnel to make it fit. To nice of a car. So I'm sticking it in the truck. If there's any helpful tip or tricks let me know.

Get some help put it in...them some heavy bleepers.you need the flexplate for it and spacer if it takes on(idk) new tune tranny line longer(the rear line)..that's all i can think of
The driveshaft will turn considerably faster in overdrive gear, so get a good well balanced driveshaft!
Thanks. I guess I'll have to buy a new drive shaft? I was thinking about that tonight. Both motor and tranny came out of the same truck. I got both computers,pedal ,maf,serpentine set everything for under $2,000 43,000 miles on truck. I sure hope it fits. Worst case I could trade it for a 4l80
What do y'all think of the 6l90? Better than the 4l80. Better gear range. What gears should I run. It has 3.42. I will be running the stock 454 ss wheels. 15 inch . I want the truck to look stock
If its gonna be a track truck 4l80. If its going to be mostly street 6l90. At least thats how I look at it. Keep the 3.42s because the 6l90 has a 4.02 first gear and with im guessing 26-28 inch tire its going to go thru it pretty quick.
4.8, TSP 220, 6L90 swap, 3400 Stall, 4.10s w/30" drag radial and T76 @ 16lbs.

Mostly street. I need to put a locker in the rear. I think the 3.42 will work just fine. That 10 bolt will hold up for awhile. I wish I could put my 14 bolt out of my max in it. I don't want to change the lug pattern.
