Default 427 r

I have one for almost 2 years now. It doesn't like low rpms for local driving...below 2k. It reminds me of old time race engines. I set the idle a little higher around 1k and keep the operating rpms for simple cruising around town between 2-3k. If you do that, you will be fine. Its quite impressive when you push it to those higher rpms. Bottom line.....leave the cam and motor alone.
