This is actually a division of the company that that makes pivotworks bearings. They are already very well known for making awesome connecting rods, they just haven't made a whole crankshaft before until just recently. As for bore + stroke it is done everywhere!!! Powroll does it for their kits (look at the page for the stroker info), FST does it for their kits, and so does alba. The best way to increase the displacement is by a even amount of stroke and bore. Too much stroke will cause your motor to rev very slowly and too high of revs will damage it. Too large of a bore will make your cylinder walls too thin and overheat. As for being fishy there isn't anything fishy about it, this is a already very well known company for aftermarket rods. In actuality this crank should be able to handle much more **** than the stocker (most kits use a modified stocker), which will enable your motor to take more abuse from insane riding and heavy mods like nitrous. The connecting rod is many times stronger than the stocker, and the bearings are made to take a much heavier load.
