We use our own range of cam profiles & some Alperform cam profiles for our DB2 to MkIII Fast road engines & more Modified engines, these are chilled cast iron as the Original shafts (not steel cams as they don't last) for best wear characteristics.

We have a lot of information on Aston Martin Feltham OE camshafts, their best timing position & the correct valve clearances (not AMLs data in the workshop manuals) for STD engines,

We have also amassed a great deal of information on cam timing for DB4 to DBS 6 with our engine post rebuild dyno testing.
