Ladies and gents,
Many of you will have known John Brown, a long term humpy enthusiast and collector of a wide assortment of early Holden gear (not to mention a great bloke). I have been fortunate enough to have visited John prior to him passing away… a trip to John’s place was like walking into Aladdin’s cave. An overview of the collection has been published previously in Street Machine magazine. John had been slowly cataloguing his collection, both by photographs and by hand-written notes.
For this first post, I will concentrate on John’s inlet manifolds. Exhaust manifolds to follow.
The photo below shows (from top to bottom):
1. A Thomas twin two-barrel carburettor inlet manifold to suit Holden grey motor. This manifold does not retain the original “hot box” exhaust gas heating.
2. A Gibson & Co. Gibson Superpower single two-barrel carburettor inlet manifold to suit Holden grey motor. WL 6354 relates to Gibson’s telephone number. This manifold retains the original “hot box” exhaust gas heating.
3. A Gibson & Co. Twin Superpower single two-barrel carburettor side mount Stromberg inlet manifold to suit Holden grey motor. Note the north-south orientation of the carburettor compared to the east-west orientation in the similar manifold above. WL 6354 again relates to Gibson’s telephone number. This manifold retains the original “hot box” exhaust gas heating.

The photo below shows (from top to bottom):
1. An unbranded triple B-model Stromberg carburettor inlet manifold to suit Holden grey motor. This is possibly a unit manufactured by SJ Brown. Note that this manifold orients the carburettors at 90º (float bowls pointing east-west) compared to the normal orientation. This would make the float chambers very susceptible to fuel slosh during acceleration or deceleration. Note the lugs cast into the outside of the manifold plenum to allow a divorced throttle linkage bar to be mounted. This manifold does not retain the original “hot box” exhaust gas heating.
2. A Cain triple B-model Stromberg carburettor inlet manifold to suit Holden grey motor. This manifold also has lugs cast into the outside of the manifold plenum to allow a divorced throttle linkage bar to be mounted and does not retain the original “hot box” exhaust gas heating.
3. A Speco triple B-model Stromberg carburettor inlet manifold to suit Holden grey motor. This manifold also has lugs cast into the outside of the manifold plenum to allow a divorced throttle linkage bar to be mounted and does not retain the original “hot box” exhaust gas heating.

Like the Auto Carburettors manifold above, this manifold also has lugs cast under the manifold plenum to allow a divorced throttle linkage bar to be mounted and does not retain the original “hot box” exhaust gas heating. Note however the differences in the main plenum under each carburettor and the different runner shape.
2. An unbranded twin B-model Stromberg carburettor inlet manifold to suit Holden grey motor. This manifold also no lugs cast to allow a divorced throttle linkage bar to be mounted (i.e. is likely to run a married linkage), and does not retain the original “hot box” exhaust gas heating.
3. An unbranded twin B-model Stromberg carburettor inlet manifold to suit Holden grey motor. Again, this manifold has no lugs cast to allow a divorced throttle linkage bar to be mounted and does not retain the original “hot box” exhaust gas heating.
The photo below shows (from top to bottom):
1. An unbranded twin B-model Stromberg carburettor inlet manifold to suit Holden grey motor. Again, this manifold also no lugs cast to allow a divorced throttle linkage bar to be mounted and does not retain the original “hot box” exhaust gas heating.

3. A Speed o Motive (later John Cain) twin B-model Stromberg carburettor inlet manifold to suit Holden grey motor. This manifold has lugs cast into the outside of the manifold plenum to allow a divorced throttle linkage bar to be mounted and does not retain the original “hot box” exhaust gas heating.
The photo below shows (from top to bottom):
1. A Hanrahan Special (Melbourne) twin B-model Stromberg carburettor inlet manifold to suit Holden grey motor. This manifold has lugs cast into the outside of the manifold plenum to allow a divorced throttle linkage bar to be mounted and does not retain the original “hot box” exhaust gas heating.
2. A One of Two Arbies single or twin B-model Stromberg carburettor inlet manifold to suit Holden grey motor. Either the mould wore out, or someone was having a bad day when the mould was made, as the letter “C” is missing from the word “Carbies”. This manifold has no lugs cast to allow a divorced throttle linkage bar to be mounted, though does retain the original “hot box” exhaust gas heating. This type of manifold allows either one or two Stromberg carburettors to be used. The unused positions are blanked off. These manifolds are often mistakenly advertised as triple Stromberg carburettor manifolds. However, the spacing between the flange centrelines is too small to allow three carburettors to fit – the float bowls clash with the back of the adjacent carburettor body.
3. An unbranded triple two-barrel carburettor inlet manifold to suit Holden grey motor. This manifold has no provision for balance tubes between the three inlet ports.
The photo below shows another view of the triple two-barrel carburettor inlet manifold shown above.
RIP John.
