Euro engine

You are quite wrong... EURO '85 engines are 4.7L

Yup, I stand corrected (twice).
Always more to learn, apologies for posting errata this time.

Concur with that, too.

Steve,

There is always more to learn and I was not trying to be an A$$ about it... If I came across that way I apologize! I am going to just go ahead and SAY IT OUT LOUD RIGHT NOW... I don't know everything! There I admit it! LOL!

I AM however, working on an iPhone app that knows more than me about 928's and it will be out in 2 months if all goes well as we start to see the finish line on this project... It will answer most all your questions about 928's or connect you to a place that does!

The beauty of using a 4.7L block is that up until '85, the flex plate migration was SUPPOSEDLY limited by use of a system of circlips and washers. That is one reason you very seldom hear of Thrust Bearing Failure in 928's older than '85. In '85, for some reason, they discontinued the circlip/washers and the TBF became more of a problem. (my '84's have the circlip)

Of course, the downside to using a 4.7L vs a 5.0L block is the lack of low end power, but you should be used to that since you have already been driving a 4.7L.

I have always wondered why the circlip/washer assembly could not be reintoduced to the breed as more torque tubes go bad and are replaced.

Dave, I hope you get your Euro back on the road soon.

Steve, as James has already stated, I too hope I didn't come across as an a$$. Not my intention at all. Just trying to help a brother along.

And thanks all for the clarifications. No offense taken!
I'm of similar mind, if I had it all down pat, I'd be bored and moving on to a different type of car to fawn and get frustrated over!

4.7 liters versus 5.0 liters [286 versus 302 in my language; I was born in Detroit] isn't going to make much of a difference in torque. The intake and cams make a far bigger difference.

Dave my advice would be to use a stock engine.
If you want more power you and do a few mods that will help.
removing the Cats, keeping 16 rims on gives you more torque then 17"
