‘A’ Coupe with Dual McCullochs
Featured in Nov 1964 Car Craft (and featured on the cover as well) this coupe sports dual McCulloch VS57 units on a dual four barreled Ford 312 cid Y Block engine owned and built by Dick Patterson. I guess by 1964 the McCulloch VS57 units would have been pretty cheap to pick up, having been superceded by the D0-VS59 and SN60/62 units.
Engine shot of the ‘A’ Coupe
This shot shows the engine and supercharger setup in more detail. As can be seen a single idler arm is used for belt tensioning, and the outputs from the blowers are fed into separate carbs using stainless tubing. The brackets used for the mounting the blowers appear to be homemade, and my only criticism is that the VS57 units are not mounted correctly, in that the badges should be positioned at the top of the blower.
Jack Schleich’s 1949 Olds Powered Deuce
This shot (fairly obviously) appeared across two pages of the March 1959 Custom Rodder magazine. Not many details were supplied, only the fact that the power plant is a 1949 Oldsmobile unit, and a single four barrel carburetor and four fuel pumps! were used with the McCulloch. Nice looking rod though.
Dual McCullochs on a Drag Car
I guess this one was for the strip only as uniquely not only does feature dual McCulloch’s, it also features dual engines! Unfortunately I have no information on the set up, only the fact that the engines had to be kept in balanced tune to keep an even power flow to the rear wheels, and the fact the car was run at the NHRA Championships in 1959.
Tommy Edwards Buick powered Model ‘A’ Roadster
A nice close up photo of a Tommy Edwards ’53 Buick powered Model ‘A’ roadster with McCulloch VS57 blower. This was a successful racer during 1957 and 1958 and the engine modifications reported for the car were a Lishin 1907 special grind cam, chopped flywheel, Magspark Ignition, and homemade headers.
Dual VS57 Setup
It’s difficult to identify the host engine used on this dual VS57 setup photographed at either Bonneville or the National Drags in 1958. Note that the blower outputs are neatly paralleled by feeding both outputs to both carburetors, giving an increased air flow, and allowing the boost outputs of the McCulloch,s to be turned up. The use of separate belts and idler pulleys on this setup would cause clearance problems if it was used on a standard automobile.
Another shot from the 1958 National Drags or Bonneville meets, this time of a Hemi installation of a McCulloch VS57 unit. This setup actually uses Hilborn fuel injection in conjunction with the VS57 with a custom steel airbox being used to channel the blower output to each of the injectors.
Tommy Edwards ’53 Buick powered Model ‘A’ Roadster
This great cover shot came from the front cover of the first issue of Custom Rodder magazine from May 1957. The car’s nickname was the Blown Banshee and from the looks of it would have lived up to it’s name. A b/w photo of the car is featured earlier.
McCulloch Powered Rail
A photo of a McCulloch powered rail published in May 1960. I’m not sure about the engine or the induction setup which looks to be using a hybrid of a carb bonnet in conjunction with an air box. Any ideas?
Benny Appollonio’s’33 Ford
A 1959 photo of Benny Appollonio’s McCulloch blown 3-2 setup on a 1955 Olds powered 33 Ford competition rig. Multiple carburetion in conjunction with a McCulloch was often a popular combination for drag racing during the fifties, and it certainly gave presence when seen on the strip. I suspect this particular setup would have resulted in reduced boost due to the squarish U turn in the ducting, and that gauge would certainly have given an inflated indication of the boost actually achieved in the manifold.
Jack Schleich’s Dual McCulloch 32 Coupe
Jack Schleich sure had a love for the McCullochs (see his ‘49 Olds powered Coupe near the top of the page) and by 1961 had progressed to a dual setup, or more radically a dual McCulloch into six carb setup on a ‘60 Olds mill. The VS57 units feed three carbs each via custom carb bonnets, allowing them to be run at a higher pressure without being too heavily loaded with air flow demands.
