There is a adapter kit available somewhere that will allow a white block engine (the 850 one) to replace a red block engine (as in 360's), so connecting it up would be alright if you had a 360. For a 340 you'd need to change most of the drive line.
You'd need some custom mounts in order to fit the engine into the engine bay, but someone experienced in such matters wouldn't have too much trouble. I have no idea about the length of the engines though and if it would physically fit without major changes.
It'd make a super car though, as those 5 cylinder engines are great and sound awesome.
