I bet that would be a fun one. You'll have to post some videos and keep us posted when you get it in and driving. I have been a advocate of small cams in 273's (and 318's too) but I'm changing my tune after chatting with guys like yourself that think outside the box a bit and try a bigger cam. That Xe262 has duration @.050 close to that 220° magic number that we all talk about. You can go bigger in a 273 but you will for sure need a converter and/or gears to make it work.
