    Advice on clutch for 71 with a 2.7?

    Hey all - I'm building a motor for my car. Right now it has a 2.7, basic setup with carbs. Trans is a 911/01. Trans has been rebuilt and has a billet center bearing carrier. I don't launch 1st car. It will get an LSD + reinforced side cover too.

    So I'm curious on clutch. if I understand, these use a 225mm clutch different than the 901. What I want is a clutch that could take an RS spec+ power, but not be heavy, or 'hair trigger'.

    Looking at options to clutch, PP, flywheel, etc.

    Thanks

    IMO don't use a Sachs sport pressure plate . The '70 , '71 push style release fork and cable are not up for the sport PP .

    Yeah this is the sort of info i'm curious on, if stock is "OK" or what can I do to ensure I have adequate gripping. The clutch in there now I ease into it, it doesn't slip under load. It did when i first got it and needed adjustment. Which its nearly out of.

    The stock 71 clutch is more than capable of handling the power from a 2.7.

    Sufficient for ~250hp(knock on wood)? This will be a pretty hot 2.8 build.

    Thanks
