your best bet would to do a 4l60 to 4l80 conversion , it cost bout $600 minus the 4l80 tranny (check junkyards) and labor
you could buy a pre-built up 4l60 or 4l80 too but they tend to be alot more money.
btw if your truck has the stock 10 bolt , say good bye, plan on buying new gears for it or switching the axle over to a 14 bolt.
400+ hp on going to the 10 bolt and towing/racing/off roading kill the spider gears pretty bad , I know form experience![]()
