500 stroker?

I have been looking at what I want to power my Barracuda with on my current build it had a 440 in it. It is a 67 notch back but I ran across this stroker kit for a 400 that bumps it up to 500 cubes it comes with a crank, rods, pistons, bearings and rings for 1600.00. I would have more clearance under the hood for headers, etc. and weight about 65 lbs. less I think up front. Anyone used one of these or know anything about them?

thanks,
