Are you refering to the SHO Shop 3.6L stroker motor? If that is the case, most of them had an early demise. They had issues with the crankshafts due to being cut and rewelded. There is one that is still running (that I know of) in a Gen 2 ATX. At least as of last summer.
I should also note that it is likely that they are not even selling 3.6L any more. Besides the "specials" section that website does not get updated anymore. Many of the products listed have been discontinued. For more information regarding SHO Shop, run a search in the archives here at SHOForum. Customer testimonials speak volumes.
