It's a stock GMC/Detroit Diesel piece. Not necessarily 'vintage' either. It's for a 53-series Detroit and by the looks of it, I'd guess, probably for a inline 4-53 or possibly, maybe, a V-type 6V53. They're nice little blowers, but compared to the bigger '71 series' blowers, they're a lot harder to adapt to use as a supercharger because there aren't any *commercially available* intake manifolds or belt-drive set-ups for them.

Thanks. It is the 4-53. I've been searching for "arrow" due to the logo in the casting but came up empty handed
4-53, you will find several threads if you search. I had one and sold it to another HAMBer last year.
You will also have to rig up an oiling system for the bearings on these. Not sealed like the bigger Detroits.
My 6v53 has a longer case and some other difference from that 4-53 blower. I do have on it a new aftermarket parts from Joe-Blow's Speedshop in Australia. I still have a bit to go on the completion of the rebuild.
ohio george ran one of those ,, on a sohc ford in his 33 willys ,, built that model kit at least 3 times lol fabricator john miss you dad
Sorry but you are incorrect. Ohio George ran a pruned 6-71 made of magnesium. Basically a standard GMC with the mounting flange milled off and bolted down from the inside of the case. He went in with Sneaky Pete Robinson and cast 200-300 cases. They also made magnesium bearing plates.
