46 MM webers to big? Weber guru needed.
I bought a project car that has 46 MM webers on a 2.7 911 S motor that had cis on it. So this is a "late" S motor. Would it be possible to use these carbs or are they just to big? Here is the "kicker", I am at 4500 ft elevation. I'm planning a rebuild so I can make some changes but want to leave it a 2.7. Any help would be appreciated. Also if they will not work I might want to do so trading!

too big for even a 3.0 really, at least in stock form.

I would say that they're too big - I had a 2.4S engine which had been upgraded to a high compression 2.8 twin-plug & found that 40 IDA's were more than adequate.

Bad news they are too big for stock motor. Good news is they are worth good money.

Looks like I'm on the hunt for 40mm carbs. Anybody got some PMO's to trade?
