Main chassis
Side tubes united at the front by complex cast magnesium bulkhead, supporting fabricated steel abutments for front suspension coil springs and links, steering rack etc. Spare wheel on top fulfilled 1967 regulations

Oil tank
Rear-mounted dry-sump oil tank attached to left-side rear chassis tube extension, moved soon to the right to bias weight to the inside on clockwise circuits

Engine
The fuel-injected 4-cam 90-degree V8 originally emerged in 2-litre form for these 1967 ‘Periscopica’ prototypes, and was progressively enlarged to 2.5, 3.0 and – for CanAm racing – even to 4-litre form in subsequent T33 variants

Chassis
The big-tube H-frame centre-section chassis structure was unique to the 1967-68 Alfa T33s, initially in 8in diameter aluminium, replaced for ’68 by similarly sized rolled and welded titanium tube. Fuel was housed within…

Driving position
Somewhat perversely the ‘Periscopica’ T33s featured left-hand drive… placing the mass of the driver unconventionally on the outside of the car in the majority of corners on predominantly clockwise world-class racing circuits. Alfa Romeo betraying its production car habits?

Bodywork
Body panels for the T33 ‘Periscopica’ cars were curvaceous, well proportioned and moulded in glassfibre instead of being hand-beaten in aluminium as had been the Italian tradition right into the mid-1960s
