In response to Jim.Biron

Sorry, but a cam with 226/228 duration at 0.050" is not going to sound 'lumpy' in a 383. However with good induction, heads and exhaust it will still make serious streetable HP.

I run a Comp XE274 cam which has 230/236 duration at 0.050 in my 383 and if the carb is tuned right it only has a slight lope at idle.

If you want the 'race car' idle sound consider a cam in the 238/244 duration at 0.050 range.
