A friend of mine has a chance to pick up a flathead V-8 McCulloch Super Charger.We haven't seen the unit yet...It was built in 1938..Guy wants around $3000 for it...I don't know what its worth or how to tell if it's functional...any help would be greatly appreciated...D32
Make sure that it is complete. If it's like this one it will be damn near impossible to find things like the generator mount and belt tension ideler.
For that price, make sure all the parts are there. Blower, intake, belt tightener, bottom pulley and whatever else. Seems like the price may be alittle high but you can't get them at jegs. They don't put out alot of boost but look neat. I have one on the shelf but have not got around to putting it on yet. Neal
Heres another thread, has pics and some links to McCullogh website for further info Like the man said that old a unit will be exceedingly hard to find parts for. http://www.jalopyjournal.com/forum/showthread.php?t=16210&highlight=mccullogh On an early flathead size engine they will do enuf boost.
No I don't but Norm Frick of Flatheads Forever was making multiple belt pulleys for flatheads. That was my plan. I sold this unit less the carbs, generator and Y adapter on Ebay for 3500 a few years ago. So at that time there were 2 guys that wanted it that bad. Who knows what anything is worth. Especially in today's fearful economy.
Re the crank pulley - Size is kinda crucial. Too small and you wont get the boost you hope for and too large you can over rev the thing. Dont know for sure about the 30's model but the VR57 I have was very sensitive to over revving. Its internal oil pump piston could float and starve the unit VERY quickly.
I bought 2 units for that price ... see pics on post #15 http://www.jalopyjournal.com/forum/showthread.php?t=244319&highlight=mcculloch
There are several different variations of the early McCulloch supercharger for the flathead. The model numbers usually have the year and the intended application. For instance, you might have a model number 38F, which would be a 1938 version for a Ford. A later version could have a model number such as 39 M intended for a Mercury. The later versions have a special intake manifold that is specially designed for the McCulloch blower. The earliest versions use a standard 1938 Ford V8-85 intake. The one pictured above is a late version. <?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o> The earliest versions also mounted the generator on the head, about halfway back. The special mounting bracket is extremely rare.<o></o> The crank pulley is special with 3 or 4 grooves depending on model. The 3 groove water pump pulleys are also difficult to find, but you can get by with the 2 groove model 79 truck water pumps. <o></o>
