ive heard alot of different views on this fro alot of people some people say it spins with the wheels some say it spins against hense y when u decellerate the the engine spinnin backwards helps slow you down... the reason im asking is ive come to dial my 286 cam in and need to know which way to turn the cam when im doin it. i.e the vizard way. thanks very much.

Yes!!!

If you're standing by the passengers side wheel, facing the drivers side then the engine will be turning clockwise!!!

The engine never spins backwards - a good way to think of an engine is as an air pump that just happens to also be a muzzle loading, piston firing, cannon. If you barely load the cannon, like when your foot is off the go pedal then driving the pump with the road wheels uses up energy and slows the car down.

Looking at our cyber Mini, from the left side so we can see the fan we'd notice:

The road wheel going anti-clockwise when moving forwards; so the diff crown wheel is also going anti-clockwise; it's driven by the pinion (going clockwise) and in 4th that will be solidly connected right through the gearbox to the input (or 1st motion) gear. That's driven by the transfer idler (anti-clockwise);which is driven by the primary gear fixed to the crank by the clutch (back to clockwise); so looking at the front end of the crank (nearest the radiator) - it will also go clockwise.

Clockwise from the front.
And the front of the engine is at the radiator side,

Think of how it's have looked mounted longitudinally in a car, fan and radiator at the front, and clutch at the back.

This is also why cylinder numbers go one to four right to left.

Stop-it, I almost wrote inline, then went for longitudinally.

Thing is we use them interchangeably at work, and the context generally give's it away!
