1275 A-Series Camshafts
We now carry new steel billet performance cams for the 1275cc engine that are tailored to performance street driving. These cams mate up to the latest design A+ slot drive oil pump, and must be installed as a set.

A bit of history on the A-Series engines:
The A-Series engines started out at 850cc, then were increased in steps to 948cc (Sprite/Midget), 998cc (Mini), 1098cc (Sprite/Midget, MG1100), 1275cc (Sprite/Midget, Austin America, Mini Clubman).

The rare 1275cc Mini Cooper S was a unique engine that had a lot of differences from the later 1275cc engine that is so popular with Spridget owners.

In 1980 the much improved A+ engines were released both in front wheel drive 998cc (Mini 1000) and 1275cc (MG Metro) configuration and as an in-line 1275cc (Morris Ital).

(A+ engine blocks can be easily identified by external strengthening ribs on each side)

Matching slot drive oil pumps:
114-039 Turbo High Output Slot Drive Oil Pump
Originally fitted to the MG Metro Turbo, this pump provides more flow than stock which keeps oil pressure constant under hard use and is a performance upgrade to the stock pump.

114-034 Slot Drive Oil Pump
This is the standard pump as fitted originally to the A+ series of engines. It is an improvement over the earlier 1275cc star drive pump.
