David, I'm glad to hear you are happy with your present camshaft setup. I
would not sell anyone something I don't believe in, and I stand behind the
pinning solution 100%. In my opinion, welding is not recommended for the SHO
camshaft, or any other camshaft for that matter.
While welding seems to be an economical solution, be prepared to face the problems that welding camshafts can produce. Welding camshafts in the car (cringe) can introduce flash/metal particles into the heads, whether they are open or covered. The more serious problem that is probable with this process is cam warpage. With the extreme heat generated by welding, warpage of the camshafts is a chance you take by welding. With new cams ranging from $1000+ and up, that is not a chance we are willing to take or inflict on you, the customer. It may even warp ever so slightly, and you may not notice it at first, but will notice a couple of years down the road. I can assure you, there is a very good chance of cam warpage with welding.
The Roll-Pin solution is simple and final. The $499 spent is very inexpensive compared to the price of a new engine. The reason for the $499 price tag is because of the material that is used when making the camshafts destroys a drill bit during the pinning process. If there was a more cost-effective solution to the process, I assure you we would have been using it. Be careful of what you pay for, you may just get it.
On another note, we are also offering a new camshaft profile for the V8 SHO. It's not up on the website yet, but we are offering a Stage I/II (Stage I intake/Stage II exhaust) hybrid setup similar to the V6 SHO setup. You also have the option of this setup during the pinning process for $1299/set, including lash caps and the Roll-Pin solution. At this point I'm not sure if we will be accepting welded camshafts for this process. We will be requiring your cores in advance for pinning/cam grinding.
If you have any questions, feel free to contact me at SHO Shop 714-894-8415. Sorry, due to the high volume of email received, I have a hard time participating on the forums/lists in a timely matter.
