1968 '340' Barracuda vs 1968 '383' Road Runner

I've owned and worked on several GM's, but this one always intrigued me the most. Especially the similarity to the 340......

Bore ..... 4.057
Stroke .. 3.385
Rod ...... 6.00

I think that one is considered the "Ram Rod 350" right? That's a bad mo' fo'......I've got a magazine article on a Cutlass with this engine and it does amazingly well in the Pure Stock Drags.
