Inlet camshaft, Racing type
A racing-spec inlet camshaft for the bottom end, cataloged 1970-1971, also known by its older E11063 part number.
71-1063 is an inlet camshaft listed in the catalog as a racing type, appearing in the CRANKSHAFT AND CONNECTING RODS figure alongside the rest of the bottom-end hardware. This is the older E11063 part under Triumph's letter-prefix numbering, now carried as 71-1063.

As an inlet cam, this part controls the timing and lift of the intake valves, working off the same timing chest that drives the exhaust cam and the rest of the valve gear. The catalog marks it specifically as a racing-spec grind rather than the standard road cam, which means it's cut to a different profile than the stock inlet cam it would otherwise sit alongside.
Our catalog record for this one covers appearances from 1970 into 1971, but it doesn't spell out which specific model or engine it was fitted to beyond that. If you're matching this against an engine, give us a call and we'll confirm before you order.
