Ram Air V rods are .455" longer than stock 6.625" rods.
But the original Ram Air V 303 7.08" length rods that I have are much thicker towards the big end (like an "A" shape). /\
These are shaped like (and almost look like) SD455 rods with the 7.08" 303 length and a big end shaped more like the heavier RAV rods. Probably a prototype - definitely cool.
Neat rods, whatever they are. I'd love to have them in my collection, if they ever became available (hint, hint).
