Hi Bob,
With the engine numbers we've got it.
901/01 and 901/05 use the E cams. This is the cam that opens to 1mm at 29* BTDC and closes at 39* ABDC for a 248 degree duration.
So that setup is 4.3mm.
901/06, 07, 14, and 17 use a milder lower hp cam. Opens at 20* BTDC and closes at 34* BDC, for a 234 degree duration.
This setup is 3.15mm.
901/02 and 08 is the hot S cam, opens at 38*BTDC, closes 50*ABDC, for a 268 degree duration. The setup is 5.2mm.
901/03 and 13 are the lowest hp of the bunch. The "T" engine. Opens at 15* BTDC, closes at 29* ABDC, for a 224 degree duration. Setup is the lowest at 2.5mm.
All this from matching the motor numbers with Bruce Anderson's published spec's in the "Porsche 911 Performnce Handbook"
It's the old story, some of the info is in all of the books. So you must have several books to get all the info.
Nice work, we got em all.
