Engine Decode?

My car was a 273 Commando/auto car but here's the thing. When I bought it there was no motor or much of anything related. ;) It did come with the original ball and trunion trans but I won't be using it. The 318 came with a good 904 and a drive shaft (which will have to be shortened) so I plan on using it. The carb and kickdown linkage might just take some scrounging though. I'm not using the original floor shifter though, I already sold it to a fella down under. I have a B&M shifter aready installed in the car that I just need to find some brackets and cables for and I have a line on those for when I need them. I've never taken on a project of this size and scope so it's been a real learning experiance for me. I hope I can get it on the road before I die of old age.:toothy10:
