LT1 and LS1 conversion Manuals ?

I have a 94 Buick LT1 w/ 4l60e and I am wanting to put it into a 67 El Camino. Does anyone know of any manuals on how to install a LT1 or LS1 into an older car? I want to keep the factory speedometer which is cable driven and the 4L60E has a electronic speedo. I know they made books on how to put camaro TBI and TPI engines into S10's but they came out before the LT1 was popular.
