G'day,

I contacted Dick Paterson and he gave me permission to publish the following
info:

Distributor Specifications
Type: HEI - Modified
Application: GMC Motorhome
Engine: 455 Oldsmobile
Final drive: 3.07
Tow: No

Initial setting: 12�

RPM Advance
Centrifugal
800 2�
1000 5�
1250 10�
1500 12�
1750 13�
2000 14�
2250 16�
2500 18� 30� = Total

Vacuum
6" 0�
8" 2�
10" 6�
12" 10� 40� = Intial + Centrifugal + Vacuum

As I understand it he has developed a number of different curves for GMC's
with different final drives and whether they tow or not.

Please don't ask me ANY questions about this as other than the info provided
above I don't have a CLUE!

Regards,
Rob Mueller
