Hello all. I was checking out all the mods that everyone has done on their 450s. I seen some posts about a 488 kit and a 500 stroker kit. I can not find any furter info on this kits. If someone could give me some info and were to find them that would be great. But due to the lack of oil in the crankcase for some time. Game over! I have not ripped the engine apart but it is in the back of my truck. Out of the wheeler. I suspect it will need a new crank. So why not stroke it right? Thanks for any info.
