It depends what you want...if you would like to have a Mercedes feeling around idle then it is the wrong Motor...but with the cam swap it can be very smooth. I have a 427R and was in the same boat. My target was to have a driveable car and it was working without a cam swap. I would start with small and cheap Things...check timing and timing curve...carburator adjustment, checking power valve, idle up to 1.000rpm and then try if it is ok for you. If not ...next step...cam swap and fighting with warranty.
