Not Ranked
I really think either engine will adjust the later date sale price accordingly. The 390 big block being less expensive would probably sell easier.
I'd get the Roush 427R and do it up just like the last one I had. Unless you're looking for better fuel economy I'd step away from the 427SR and 427SRTW.
