Isn't there a guy working on casting new 3.6 cases? Maybe he could cast one for an 8

Yep, That crank won't work in two T4 cases welded together, the distance between throws is all wrong.

Flat plane crank V8's were noisy and vibrate badly, there has been a resurgence of FPC V8 in high end sports cars but I can imagine they are using balance shafts.
Also I bet in alunimum blocks they are casting in steel bearing saddles, much like in the 996/997 crank carrier.

Back to the flat 8 talk....

Found out Ferrari uses flat-plane crankshafts in some of their V8's so I went on eBay and voila... I found this crank from a 328, 73mm stroke instead of the Porsche 908 66mm stroke.

Guy wanted $850 plus shipping, I offered about half that, he didn't quite tell be to F off, but I think he wanted to with his response, asked me to call if serious.

Anyway, while not as accurate as the 908 crank it seems like a cheap alternative.

There are people reproducing basically all of the parts of the 908 engine. You don't want to know what they cost....

There was a guy, Richard I think, who used to show up at the G&R all the time who planned to build an 8 cyl. type IV. Richard are you out there?

Sort of here.
In Scotland.
This is on my very short list.
While I would love a done crank, like mark said, we would need to see it fit the case.
I am still planning two cut and pinned type 4 cranks just to piss everyone off.
I will dig out two cases this summer and get this rolling.
Like Mike, I believe this needs to be done.
I think of it as a contribution to the community, and I really need to get these drawings out of my head so I can fit in more daily shit.

Eliot,
What color should I paint it?

I know there was a Swedish guy building one and putting it in a buggy. Not sure if it was based on T1's or T4's.

edit: found this when searching....
