All MED camshafts are machined from cross-drilled steel blanks, never re-profiled, so you can be assured of the highest quality product. The following three profiles have been developed specifically for road use with over 35 years of A-Series experience. We firmly believe our cams are the best on the market for any road-going A-Series engine.

  • MED HT - An excellent road camshaft, 256 duration with a power band from 1000-6000rpm
  • MED RS - Our Road Sport camshaft, 264 duration with a power band from 1250-6500rpm
  • MED XT - Our track day camshaft, 280 duration with a power band from 2500-7250rpm

See the Additional Information tab for further advice.

Which camshaft should I choose?
It's entirely dependant on your driving preferences and the spec of the other engine components. Road trip mile muncher or daily driver? The most civilised HT profile would be ideal. Fast road car for country lane blasts? RS makes a good compromise. Fast road/trackday/rally car for the weekend? Go for the XT. A more conservative camshaft spec can often result in a more enjoyable driving experience on the road, as the power band is lower in the RPM range. 

How much power can I expect?
It's impossible to answer without knowing the exact spec of the engine and the quality of the rebuild. However, for a rough guide, if we were to take an identical 1380cc high performance road engine with a modified head, re-worked crankshaft, single HIFF44 carburettor and 1.5:1 roller rockers, the following peak outouts could be expected:
HT - 100lb.ft/100bhp
RS - 100lb.ft/106bhp
XT - 100lb.ft/112bhp

Which engines will this fit?
All BMC A-Series and A-plus engines, with the exception of eight-port head conversions and late Rover MPi Minis (1996-2000). Standard 850 engines do not use camshaft bearings, so you will need to line-bore the block and fit bearings. Contact us if you're unsure.

Can I change my camshaft in situ?
It has been done, but we wouldn't recommend it. 

Do I need to fit 1.5:1 rockers?
Our camshaft profiles have all been optimised to work below 1.5:1 rockers, but it's not essential. We also supply 1.3:1 ratio rockers to cater for personal preferences and all engine builders have their own tastes.   

Do I need double valve springs?
Ideally, yes. Our uprated road springs sets are highly recommended to remove the chance of valve bounce at higher RPM. 

Should I change my followers?
Yes, the oil pump too.

How about adjustable cam timing setup?
It's essential; without adjusting the camshaft timing to suit the new profile, you will not be able to optimise engine performance. We offer a range of camshaft kits from Stage 1-3, which include some or all of the above components at a reduced rate.
