I've done alot of research on the stroker kits, and found that it is hard to beat the price on the Butler stroker kits, for the quality of parts that comes with them. They come balanced and ready to install. We initially looked at the Eagle branded stroker kit, but soon found out that the kit came with a Mahle piston, which is fine, but they have thin 1mm rings, which some people like, but for a street engine, my personal preference is to stick with the 1/16 rings. The compression height on the included Mahle piston is shorter, meaning more would have to be removed from the block to achieve Zero Deck. The Butler stroker kit comes with a custom Butler/Ross piston that uses standard 1/16 rings, and the compression height is a bit taller, so you can get the block to Zero Deck without cutting a bunch of the block. The Butler kit also includes the H-Beam rods, where as the Eagle branded kit includes the FSI rods. We ultimately went with the Butler 467 kit. Only about a $250-$300 difference between the two when all said and done, and feel the Butler kit comes with better parts for the little price difference.
