Les,
Any of you guys in the US know how good the Mopar rods are?

I don't know much about the strength of the mopar rods, but I do know that they used to be a popular option before Scat and Eagle flooded the "cast crank" market. If they're as strong as windsor rods, and you can get the crank ground and the rods resized/shotpeened/polished etc for a reasonable price, then I'd say go for it. The 6.25" rod will give you an excellent rod ratio. Otherwise, I'd probably stick with the standard stroke. Your cam and heads will do the job nicely.

My 398 combo is a bit of an oddball combo, using a crank with the smaller Cleveland sized 2.75" main journals. I don't know of anyone that makes a 3.9" stroke in the 3" main journal size.
