All the "bolt on blower" stories pretty much end the same and usually within about 20 hours of the beginning of the story. (doesnt matter the brand and Im not knocking the procharger its a nice unit)
Im stating emphatically NOT to" bolt on" any blower without a long list of upgrades.

I learned all this the expensive way.

I to have learned the expensive way I now have in to these motors what I bought the whole boat for. Its best to just send out the motors and have them professional built and dyno

In my uneducated perspective I can see that these could be true as a week link from too much boost. Can these limits be identified or should improvements just be made as part of the prochagers installation?

Any other tips, big and small are appreciated. thanks in advance.

Is this a carb. engine or is it EFI???

Ditto Jeff. The problem is not so much with the extra stress on the internal but the lack of adjustiblity of the fuel and timing. If it is carbed and you run it reletivly rich and with about 30* total advance, it will last a long time. A valve job with good valves, head gaskets and bolts even better and you would be good to go with the "bolt ons".
