Manley 5.4L rods

[DJOHAGIN]

Has anyone investigated using a 5.4L rod in a 460 build? I was looking at this rod:

http://www.summitracing.com/parts/MAN-14319-8/

It weights 628 grams and is "rated" at 800 hp. That is around 185 grams lighter than the "typical" 6.605-6.7 rod for a 460. I'm planning on a off-set crank and custom piston, so the odd sizes for the rod and pin diameters and width are not a problem.

My primary question would the power rating of the rod go way down because of having to use a heavier piston than the "typical" 5.4L piston?

I'm exploring different ways of getting a lightweight rotating assembly, when I came across this rod. I've been thinking about aluminum rods before this, but don't know exactly how long they would last for a street engine. I like to use the engine for deacceleration, and I know that puts a lot of stress on the rods.

Thank you for any help or suggestions,

Dave
