If your writting a book, or just out to do test motors then great go for it. Or if you want a motor that no man has done before do it. The average person who wants to do a budget motor or have something that will last, stick to the basics, dont reinvent the wheel. I cant see doing all this work just to change to a 6.2 rod length.

I think everyone's point was:
1) Physically measure your deck height.
2) Within that deck height, given your particular stroke, try to maximize the length of the rods used.
a) within your budget
b) for your planned usage (drag racing engines to be regularly
torn down can run shorter ring packs and skirts).
c) with whatever baggage regarding parts you're carrying.
The point is, long rods are better. There is no magic number. I use 6.7" rods in an FE, but the FE is stroked so my rod/stroke ratio remains 1.7:1. Is 1.7:1 better than 1.6:1? Yes. Can you reasonably expect to be able to get a 1.7:1 ration in a Windsor block? If you destroke one. Do you want to destroke a motor just for a better rod/stroke ratio? No. But if you do destroke a motor, then you should look into lengthening the rods (3.5" stroke FE's with 7" rods are out there). Within the parameters above, get the highest ratio you can and don't worry about it.
