most 450's have narrow frames for a conversion. if its your first conversion and its going to be for the dunes id think about a rappy or ds chassis, far easier to work with for 4 cyl swaps. ds has a beefy chassis from the get go and the rappies are taller than 450's. hybrid swaps can nickle and dime a guy to death. if you are really considering it, 2 things id like to mention that you spend good time on is sprocket alignment and chains and sprockets. there is a thread on the this forum atvhpjunkies.com that helps with counter shaft sprocket placement with swingarm length and angle. a good conversion with proper chain guides will have very little chain tension issues, another fix for this is a chain tensioner on a spring. also spend the money of chomo sprockets cuz replacing cases suck
