Ferrari rods are 137mm or 5.394"......there is no way you are getting a 6" rod in there I don't think...unless you cut and weld it shorter (which I've done and ran them in a road race H-D for 2 seasons BTW)
The steel 348 rods you have are pretty nice....I would just use them. A lot of Honda stuff looks like they copied it from ferrari....there might be an affordable aftermarket rod out there that is close enough to use if you dig a bit.
So I also stumbled on this:
http://www.todaracingusa.com/ferrari.aspThey have an 85mm crankshaft. No prices in sight, but if you have to ask...
Oh wait, here's a listing for the crankshaft for a measly ~$13k USD:
https://www.toda-racing.co.jp/en/produc ... erkit.html137mm rod over an 85mm stroke makes a 1.61 rod ratio... Not great for an engine turning 9,000, but Hondas go that low and turn that fast as well.
With Nick's 89mm bore kit, that 85mm crank would make 4230cc's... getting up there for a Dino V8.
To use stock length rods (since they don't list a rod anywhere) with an 85mm stroke, the Toda pistons must raise the pin 3mm. That would allow a 140mm rod with the original 79mm stroke, which makes a 1.77:1 rod ratio and about 3930cc's, or about 7.6% less displacement.
