5.3 into 97 silverado

Hi my name is Dennis I was reading some of the stuff you wrote on here. I was wondering if you could lend me some tips I have a 97 sivlerado that Im putting a 5.3, I was curious to what all i would need to get it going. Eventually i wana put an 80e in but for right now im running with the 60e and i have a guy helping me with the wiring harness. I just wasnt sure what else i would need. Thanks

I have the complete motor an wire harness i was just curious about any fuel problems or stuff like that.
