I changed the LT1 in my stocker with the "happy hooker". Works great, uses the bolts that hold the fuel rails down, looks scary because of the small bolts, but I never dropped one. If you use a swivel off of the engine picker, it is easier to turn the engine around to get it in. To change a LS1 engine, it was more difficult because of the composite (plastic) intake, the intake would have to be bolted on after the engine was installed. Myron Cottrell from the Horsepower Farm in Chaska, MN makes and sells them. Check out the web site
