Mats has been about as polite as is possible................
This forum is devoted to the rear wheel drive GTV6's, with plenty of allowance for the 75 (Milano for those who can't handle numbers for names) and the Alfetta/Giulietta transaxle cars.

The Alfa V6 builds are common to fwd/rwd. The interest goes away when installation begins in a fwd car.

You have to post pics of the 33 now.. :twisted:

Modified a 4x4 systems for rwd only? I remember seeing vids of a red 33 with a lot of noise going sideways. :)

I was just surprised to see the intermediate shaft.. :)
I think it's great that you share, as Jim said, it's all the same until you fit it into the car... :)

How did you choose 107*? Is there some Alfa spec for this?

You mentioned before cam duration is 290*? :shock: Std cams have ~247* and the ones we regrind have ~260* seat duration. Your 290* is bordering on race jobs -is this what you want?
Have a look in the Catcams list and you'll see what I mean. You can of course forget about civilized idling! Remember, these engines are next to dead in the lower range, so you are not helping it get better with these cams!
