MED A-SERIES RACE CAMSHAFTS

The 310SP, 320SP and FIA15+ are what's known as scattered, hence the 'SP', with re-phased timing on cylinders two and three compared to one and four. In extensive race engine testing, we have found this setup to be highly effective on cams with such long duration, thanks to unusual nature of the five-port cylinder head.

Each cam is supplied with a specific setup sheet in the box. If you're unsure or need further advice, please get in touch.

All BMC A-Series and A-plus engines, with the exception of eight-port head conversions. Standard 850 engines do not use camshaft bearings, so you will need to line-bore the block and fit bearings to run one of these cams.

Yes we would highly recommend a set of our specific race double valve springs, which give 245lb.ft seat pressure at 0.500" lift.

Like many classic Mini modifications, it has been done over the years, but we would not recommend it. The long duration and high lift lends these camshaft profiles to engines capable of high RPM. As such, on a road A-Series engine, the powerband will be severely limited by the smaller ports in the head and lower RPM potential of a standard crankshaft. Unless the engine and cylinder head are equally racy, it will not work well at all.

On an Arden 8-port head, the inlet and exhaust valves are re-ordered, so the cam profile is completely different to suit. These cams will only work with the 8-port head.
