I use to own performance marine, and alot of wierd stuff came in on old jet boats and V-drives this is where it came from, in the late 60's and 70's the marine market-manufactures was GM's biggest customer more L-88 LS6 even tripower engines were installed in marine use than ever dreamt in production, still today Mercruiser is the largest pusrchaser of GM performance, really the only reason they still offer a production gen 5-6 block.. I was running numbers on some stuff and found this part real odd, It does come up in the gm books, but cant ever remember a car being built??? Had to be service part or?????
