Small roots blower for smallblock

I know there are a few posts from years ago. Just curious if there are any "easy" ways to put a small roots blower on a smallblock. After buying pretty much everything to throw a turbo on my barracuda i decided it would look much cooler with a small roots blower. Not looking for maximum hp, as i doubt the stock long block can take too much boost. Was thinking a 177. Cant find any kits other than 6-71's which i doubt the stock motor could even turn over...lol. Anybody doing this? Is there finally a kit out there? Anybody have one stocked up and ready to sell? Not looking for shiny, would like to find one that appears to have been sitting since the seventies..
