Hey all guy locally has a Buick GS convert with the wrong Engine still worth buying to put 400 back in one day??? nice paint, new top, nice interior, $10k chevy 350
It all depends upon ‘everything else’. I’d figure out what it’d be worth with a BBB in it, then subtract the cost of the change. How much was altered putting in the chebby? Where’s the T400? Is the original engine available? It’ll add a little value vs. a non original BBB, but a 455 can look the part and has the obvious displacement advantage. Patrick
Looks like it has a 69 trunk. And they say mediocre bodywork, which probably means it is worse than that. Can't tell for sure, but don't think seats are correct pattern. Interior appears to be a mismatch of white and black pieces.
If you buy it, here is the grille you need. https://orlando.craigslist.org/pts/d/1968-buick-gs-skylark-grill/6485867365.html
