CAMSHAFT, FAST ROAD, LARGE JOURNAL, NEW

  • SKU: TT1405N

Late Spitfire MkIV, 1500

Fast Road - This profile is best used with Webers and is recommended for a more ‘open road' application, where the engine is allowed to ‘rev' more. Will produce 105/110 bhp at 5500 rpm, but allow for a loss of low speed torque, but improved power from 2900 rpm. We can therefore not recommend this cam for regular road use. See below for more info.

Meaning of Journal Diameter

  • Small for engines with replaceable bearing fitted to cylinder block, originally fitted to twin carb engines, 1147-1286cc pre 1969.
