I found this complete McCulloch superchager and need some help with what it goes on! They fellow said it was for a Y-block, but I am just not sure! What do people think it might go to? I can get serial number too if that helps.
Do you need me to take any better pictures of the mounting brackets? I believe they have part numbers on them...
I never knew about studebakers..... So it still could be off of a y block??? Sorry I just know hardly anything about mcculloch superchargers.
I thought the blown' 312 in a 57 'Bird was with a Paxton supercharger. Oops, I stand corrected. it was known as a McCulloch Paxton VR57 supercharger.
I saw that on eBay, too.... It's not yours is it? The supercharger itself is a SN-60 or later SN series, which means it was produced in 1960 or later. Note the shorter front case than the mid 50's VS units, and it's not ribbed like VR units used by Ford in the 1957/58 model years. Could be a replacement supercharger unit with other older parts. The VS and SN series are interchangable bolt patternwise on the brackets. If you do end up with it, I'd love detailed pictures with part numbers for a website I'm screwing together for these things...
Studebaker was natorious for using parts in production that they bought from other manufacturers. It was cheaper than being innovative, and probably helped them stay afloat as long as they did. I don't know if this helps, but maybe a worthy side note?
better pic on mounting bracket, i have an complete sales litterature of the mountingbrackets and so on from the 50ies, (rather bad copy of one.. but still good to id brackets with...)
They were also factory equipment in the last two years of Kaiser. If you dont have the crank pulley, the kit is not yet complete. There were kits sold for flathead Fords as well as the new Chev V8. I have seen two of them on Chrysler and Lincoln V8's.
Can't forget the articles in HOT ROD about supercharging the compacts. They did a couple, with both Stroppe enterprises and the Granitellis, the best of the two is in the July 1960 issue and shows the supercharger in installed. Also shows the difference between the Vs-57 version and the SN-60. The article makes it sound like the Granitellis had several kits available to install these on many different cars. Got to admit though, Stroppe's install on the triple carbed Falcon six as a blow through was my favorite.
paradise wheels in california has all old patterns and alot of parts for the vs57 mcculloch sold complete kits for virtually every v8 in the 50ies aswell as flathead 6ies and yes factory installed on tbirds, studebakers and kaisers.. i have an bracket for an olds rocket myself... they even had kits for corvairs..
Is this one that you're planning on installing on your engine? If so, I'd like to chat with you about it... specifically about the mounting bracket and pulley tension. I have a VS-57 and I'm in the process of making brackets for mine. Thanks! Oh, by the way, they sure look good polished out!
The one in photo is a 1957 Golden Hawk unit,the vac speed piston is housed in that long tube under the crest emlum,it would open and close the pulley to make it bigger or smaller for rpm. Belt ware was high and the spool bearing and it's balls would ware out,but loved the hum and boost,very cool. Some had a box around carb and other just a cap with carb float vented only to cap also.
I'd rather go to John Erb instead. I had a bad ( and expensive) experience with Paradise Wheels, and they lost me as a customer....
You guys are talking about factory systems but they made after market kits for a bunch of other applications also. The pulleys might be a good place to start. If they fit then the brackets can be checked closely.
Not to hi-jack the thread, but it's interesting this topic came up since I'm trying to identify an early McCulloch branded SN60 kit I picked up several years ago. Anyone wanna hazard a guess:
It looks like the super charger used on the R2 avanti engine. They were painted black. The carb box and all looks like the unit on the Avanti. Studebaker owned Paxton supercharger in the 60s it is a short nose unit . I would bet R2
