Fairly easy swap if you have the tools and skill needed for the job. Adapters available for W58 tranny and moter mounts available also...stock tranny and rearend "should" take up to 450hp...I have seen rock crawlers with 800hp with built W58 trans and they have few, if any problems...Good Luck, and please be careful in it when your goal is accomplished, it would be a shame to total her out after all that effort and elbow grease
