Vinny,
I was looking for an article I have, about using different manufacturer's rods, but haven't found it, yet. But, If you can find a good parts man, I'll bet you can find rods from another engine that are built tougher and can be modified to fit your engine. In the Jan/Feb 2003 12 Port News, there's an article about Charles Chandler's Model A, powered by a FH Ford six. Maybe you can contact Mr Chandler and get some pointers.
I see one glaring error in the article, though. There's mention of a 215 flathead six in '52. However, '52 was the first year for a very good OHV six, of 215 c.i. Although, it was smaller than the older FH 223, it was a strong and peppy engine.
