I have same kind of problem going on.
Only thing what I have found is that buy shopmanuals from Ebay.
Nobody is telling anything about viper engines cos is still playd by a small group of people and they usually have dollars to pay and let somebody else do the job.
I did ask around in viperalley about modifications and problems (oiling, spining rodbearings) of these engines, and soon I was asked nicely to go away
