What is a 454 BBS?  You mean a BBC?

The outside diameter is likely the same allowing for the seal to fit.  The problem is, I believe the cam sealing diameter is smaller than the crank sealing diameter.  This would mean that there would be extra pressure on the crank from the seal.
While seemingly not a big problem, this may cause the crank to develop a groove at the sealing point.  Crazy?  I thought so until I had to repair my crank on my 454 BBS.  They offer a thin sleeve to put over the crank sealing service to repair this.  I would doubt this part is available for the Audi crank.
I would suspect that an Audi crank would not wear like a 1970 American crank but you never know...

Certified factory trained Audi master technician of 25 years. I bought both, we agree that the cam seal is easy and he'll just do the crank seal while doing the tb. He tells me yesterday he forgot to do the coolant T and I blow it off thinking that's not hard to do myself.  Then today I'm going through the trunk and find the thermostat and the seal, only it's not the cam seal, it's the crank seal! He put the cam seal on the cranshaft, and said it went on without a problem. I labeled them based on PN and he described them to me over the phone.. He just grabbed the wrong one I guess.  What's the consensus on how long this will last before leaking???
