Does anyone know where I might buy a Y block blower crank hub ???

No, they don't make them, you will have to give me your blower! LOL
Welcome to the site, I think most people have to have them custom made but try Gord, Mcmillan rexrep@telusplanet.net or Chuck Cline may give you an answer, he just had one made.

58 Rack Dump, 55 F350 yard truck, 57 F100

59 & 61 P 400's, 58 F100 custom cab, 69 F100, 79 F150, 82 F600 ramp truck, 90 mustang conv 7 up, 94 Mustang, Should I continue?

Can you be a little more specific? Are you looking for the stock crank pulley for a VS or VR 57 set-up? or another type of blower?

I had one made up to add a pulley for a 4-71 on my stock balancer. I can provide measurements if you like or have him make another on. Uses all three bolts in the damper and sits flat against a double V setup. Can be made for single V too. Chuck

Heres my hub    very much similar to Moonshadows .     Uses one of John Mummerts steel dampers.  adapter is a snug  fit to ID of damper.   I added 4 more mount bolt holes to total of 6.  [ kind of overkill I guess]    2" register  to accept different pulley types..Im going to use V-belts for first attempt.     .As Moonshadow offered I can send copy of my print.also    . Regards Thundercat

I had an original McCulloch magnesium add on pulley for a guide. Made the same taper to fit into the pulley. I think I like the mounting face a bit better on Thundercats but so far am happy with mine. Chuck
