Not Ranked
You can't go wrong with Roush whatever engine you decide on, but I think all the motors make good street mills. My motor is almost identical in set-up as the 427R (heads, intake etc...) but has a more radical cam and it never gives me any problems on the street. Cruising is not a problem and it always runs cool. I would go for the 427R if it was me, but they are all good motors.
