It could be an exhaust leak and when the engine richens up it smells more. Does it smell sort of like gassy exhaust? I noticed you don't have a header. I do and mine leaks right where it meets the block. Normally I don't smell it unless I drive it hard or come to a stop after driving for a while. I know why mine leaks, it's because my friend didn't use any sealer when we put the header on. I would check the exhaust for any cracks or maybe there's a gasket going bad at your cat. Hope this helps a little.
Just noticed you only have 700 miles on the new engine, so it COULD be the engine but I don't know if it would even smell or not. You would have to ask someone who has replaced an engine before.
