LS2Sierra

Whats up people, I am in the beginning stages of swapping my 4.3 V6 that is in my truck now (2002 GMC Sierra Stepside) out for an LS2 and modifying the 4-speed automatic tranny with a 6 speed manual. Along with that ofcourse the stock driveline and rearend is going away too. But the reason I am seeking help is to find out what all will have to be changed on the electrical side of the house. I know the ECM will have to be converted over, the fuel pump will need to be upgraded and possibly the radiator as well. Has anyone here done a truck swap before? Thanks
Jeff
