With clutches sometimes things can come loose and cause a rattling sound (think broken spring in pressure plate, or throw out bearing locking tabs broken on the slave cylinder).
I have also seen a socket dropped into the downpipe during an engine swap that caused a great deal of noise at certain RPM....had to drop the exhaust to get the socket out.
I have had cat converter catalyst come loose inside the cat, causing all sorts of strange power issues and rattles, so the first thing to do is try to pin point the noise location.
You just had the engine and transmission out, so check your work!
Is the scatter shield in place properly? all bolts tight? have a good look around with lots of light and a small pry bar :)
Did you install a new clutch?
I think you guys may be onto something with the fuel pump, a pressure test will help.
Do you have an OBD2 scanner? Something that can watch things as you drive?
How much have you driven it since the conversion?
pulling spark plugs carefully and inspecting them can tell you alot!! If one looks diff then the others, or is wet with fuel, well it helps show you where to look
