Very clean Blazer! Hopefully you'll be able to drive it around soon.
I still need to do a few more things to mine before I drive it much. I have to crawl under it and put a new oil pan seal on it. The one that came with the new motor was a 4 piece oil seal. Talk about dumb! Well it leaks (no suprise). So I'll try and find a better gasket and hopefully it will seal.
