BS engine specifications

[Geoff Dowdle]

Peter,
I have a Arnolt Manual and have found a reference to the valve timing at 40- 80 -80-40 in section 1 page 8 .
Where is the Valve Timing diagram ??

I suggest you get the engine builder to set up the cam at a centre line of 110 deg and see what the valve timing is at .002 and .009 clearance . This should clarify the timing , there should be a part number on the cam .

Geoff
