I'm digging this It's pricey that's for sure https://sandiego.craigslist.org/csd/cto/d/santee-1970-buick-lesabre-ls-swap/7243973483.html
Nice: LS with a LS! 2005 Tahoe Ls 5.3 has 295 real world HP, that's more than the LeSabre every came with Maybe the seller meant that it looks original on the outside. Not sure about being pricey: it's listed for $20
