Straight 8 In a C-10 Panel

[68 C-10 Panel]

Hi guys, been out of the loop around here for a while. But the warm weather is on its way here in MI and the panel is going to get the new patch panels she badly needs. But I am a glutton for punishment and have come across a Buick straight eight. What do you guys think about this swap? I know there will be some fab for the motor mounts and such, I still want to use the 700r4 but I now have a nv4500 5 speed manual in the mix, so that's another possibility. Has anyone ever come across a c-10 with such a thing? My google search has come up empty. So I just figured that I would throw it out there and see what the experts thought. And of course here is a pic of the motor. Also this is a 263 not a 320 like I first thought, but I still think it would be cool.
