Shankle 5418 Rank 8 cam setting

Dear Alfisti,

If anyone can help?
Thanks,

Re: Shankle 5418 Rank 8 cam setting

These are high performance cams -street and slalom. rated by Shankle as 8 out of a scale of 1 to 14. Where 5 is best for street .

Firstly you will need higher performance valve springs than standard such as the Shankle 4180 or 4181
You cannot use standard valve springs as they will bind and are not 'strong' enough
And you will need new cam followers

The cams should have
10.3mm lift
Valve timing 49-67-68-42
Valve clearance intake -010 exhaust- 0.12
duration deg crank intake-304 exhaust-300
overlap deg. crank 91?
lobe centres in. deg ATDC 99 Ex. Deg BTDC 103
Duration @ .050" lift deg crank 256
