Big Block Fuel Injection?

Hey all!
I am posting here because of the increased traffic. The suburban has a 402 Big Block and I have a few questions. Has anyone done fuel injection on this setup?I think some fuel injection was done on the 454 (or was it TBI?) Would a setup out of a junkyard work on the 402? I know the displacement is different, but what if the 402 had a cam, or even a 454 crank in place? Is there a Big Block Fuel Injection setup that doesn't cost a fortune? I thought I read about some vortec Big Block heads. Is there such an animal? I'm looking to make the Suburban a bit more driver friendly for my wife and am trying to figure out some different options. Cost wise it might be cheaper to put a 5.3 in it, but I want to be able to tow with it and I think I would like to keep the Big Block. I know I could just throw a 454 in it, but again, I kinda like the idea of keeping the original 402, or maybe making it a 427.... What are my options guys?
