We check the pin depth...and I assumed every one else does as well. Very simple and obvious if it protrudes.
On the single blot, I agree that if the pin did protrude then the bolt will not hold as designed....but if correct we have single bolt cams on Ford mod motors holding 800-900 plus HP with never an issue....but that is an overhead cam design. On the Maseratti we have in the shop the cams are also single bolt and NO dowel pin....and the engine I am rebuilding right now is the same basic one used at Lemans in the day (early 60's).
I think most are missing the point here. Modifying and engine is not a simple "buy the part and bolt it on", these things are easy and obvious to check for and assemble correctly if you are an experianced engine builder so the failures I have followed to date (we have had zero....and we build race & performance engines all the time from scratch) have all appeared to be assemble error and not something I would blame on Comp or any cam manufacturer. The various timing chain/gear kits are all different (the after market ones) and it is standard to inspect fit , degree the cam, and check for proper PTV clearance. As stated before, there are far to many shops popping up that are taking on motor work w/out the properly trained engine builders in house. Many are "bolt on" techs. So I stand by my staement that the single bolt is fine and safe if installed properly. Make a mistake in ANY area of engine assy and you have catastrophic results.
