Yes it has been done. The journals have to be turned down to fit the poly then I think you need custom rods and/or pistons. I was looking into this a year ago but the expense made me just go get a 360 Magnum with FI. Cambell enterpises sells a 360 and 402 stroker kit but they are basically 3 grand. If your serious join the yahoo 360 poly group and get a hold of Gary Pavlovich he is the poly guru and can set you up.
