KB's in a 318 with No Re-balance

What about the pin retainer clips? Wouldn't that keep it from interfering with the cylinder wall? I can't find a good pic of the KB167 pin clip design.

My original thought was to make the "balance pin" out of aluminum rod installed with a light press fit. Size on size. If it did move it would only be aluminum not steel rubbing on a lubricated cylinder wall. My biggest worry about that was expansion rates between the aluminum pin and steel pin. I'll have to do more research.

When I found this post I was glad to see someone else thinking the same. Also why don't they just make pins for this? It seems like this is a no brainer to me. The same situation for BB400. Which is why I frist considered this. Now I'm looking to build a cheap 318 for my truck. If Silvolite made a 318 flat top cast piston OEM weight with 1.810" compression height for a comparable cost to the stock replacements, they would have trouble keeping up with the demand. We're only talking 318 power here. 350 hp maybe. Most builds probably won't see that.
