MGC CAMSHAFTS

There are considerable differences between new and reground cams so the decision should be taken carefully.

Reground old units limit the lobe size and position, with this in mind we only accept old units which have not been reground before, both on the lobes and journals.  Using the original material we heat-treat these to the best limits available.

New camshafts use the best material available for long life and are fully heat-treated with the lobes made as large as possible to reduce wear.

Also now available as a Billet Blank for final profiling and heat treatment to your specification, by ourselves or your cam grinder.

PROFILES

- DWR 1 profile is the only camshaft which will fit without any valve pocket reliefs.  This profile is better than the standard cam and so works well in any standard or mildly tuned car.

- DWR 2 profile is high lift with 300 degrees duration (requires valve pockets). This profile is very similar to the original 'Works' profile and ideal for rally or track day cars and works well with triple Webers for a punch of power as it comes on cam.

- DWR 3 profile is high lift with 320 degrees duration (requires valve pockets).  This profile is very similar to the DWR 2 with a little extra duration and overlap.  Ideal for race cars and works well with triple Webers.

- DWR 8 profile is a higher lift with mild duration (requires valve pockets).  This profile is ideal for fast road or mild rally and works well with twin 2"SU's or triple Webers for a smooth tractable car.

NOTE.  Followers and cam lube should be purchased separately.

Download the PDF attachment below for a Camshaft Profile Specification sheet that includes a description of the different cam profiles.

Please specify the profile required with order.
