Denn10

Hey everyone, names Dennis and im from SoCal area and i found a link to these forums from a seller on ebay who was selling chevy engines. I do have a question but not sure exactly what spot would be best to post it so feel free to guide me to a specific forum or maybe some links if this is a question thats been asked before. I have a 04 tahoe with the 4.8 and im curious about installing a 6.0 into it. Im not positive but would all the electronics besides the computer be a direct replacement or do you have to have everything from a 6.0 to put into a vehicle that has a 4.8 or 5.3? Is there a big difference in swaps from what i have to a 5.3 or 6.0?

thx
