You might want to send this to the alpine list, it was sent to me only.
I have done all the above, but with a set of 6 inch carillos instead
of a conventional steel rod. Using a stainless tig weld helps to keep
the heat down, and of course shot peening and resising helps reduce the
new stress.
I checked into rods for the chevy II engine, but nobody made good ones,
and I would have ended up spending $300 a rod for custom. It sure made
the welding aproach seem more attractive. The net mass of the con rods
was just less than stock even with the 7/16 inconel cap screws.
The size of the big end can be overcome by installing the the rods to
the pistons from the crank side of the engine. This allows you to
run the full strength of the rods.
