I am currently configuring my 3,2SS which will see 60% fast road/ 40% DE use in a 1972 911 with 2050 lbs. I will need driveability on low RPMs but due to the ratios of my 915 gearbox and the tracks I plan to use I want to spin it up to 8000 RPM - Power could start to drop at around 7600 RPM.

It will have slightly ported 3,2 heads with IN 41mm/ OUT 38mm ports and standard valves. I plan to use MFI with bored 42mm butterfly E throttle bodies.

I have two questions still left unsolved:

1. What would your suggestions regarding cam be for this one?

2. What is needed to let this engine live at periodic use up to 8000 RPM? Can I stay with the standard oiling on the crank or should I have it cross-drilled? Will I need RSR rockers? Are there any other suggestions for durability up to this RPM?

Many thanks for your help,
Chris
