69 S Mech advance Bosch Distrubutor advance curve
I am replacing my Marelli with a Bosch...
The engine is now a 2.7 with S cams so I went with the 69 S version. Does someone have the advance curve for the distributor. Bruce's book says set the advance to 30 BTDC at 6000 RPM. Any thing else I should know?

Try this:
"  " (C) 1969 Dr.-Ing. h.c.F.Porsche K.-G Remember the engine RPM is double the distributor RPM. I assume this is single plug. Do you have knock sensing? With care and the big bore, you might be able to get away with more advance. Best, Grady |

2.7 RS spec with relatively low compression, under 9.
It's funny, they only had "S". And it looks like the only difference is the rotor. SO hopefully that means I get a cap and rotor with the thing. $325 for a rebuilt.
