I am a month out from starting my 5.3 swap into my 88' 62 and I have started a spreadsheet with parts and costs. If anyone one out there has a similar list that I could reference and build off of that would be awesome. Any notes that someone has collected would be well used as well. When I get done I will put together a PDF and Post up for future reference for the rest of the mudders that want to tackle this swap. firstname.lastname@example.org So Far I have all the basics: Bought my 5.3- 04' 90K with 4L60E Complete H3 Oil pan TC Rebuild - George and Valley Hybrids lacking the Fuel filter / in tank Fuel pump / any connector list would be great.
