So i know you guys have heard this question countless times. So here is what I am doing I am building a LS2 402 C.I. Block I don't know weather I am going N/A Or a roots magnacharger SO i need help picking a cam for both. and on top of that note I don't even know whats heads I need to run so maybe a good head for either application I would like to have an almost choppy idle but can still get a good tune out of it and fair milage so a good rpm band will be good too.

Thanks
Randy

AFR or Trickflow head, if you want a choppy idle get a cam with a narrow lobe like a 108-110 for a N/A motor, not sure how high you want to rev it, but bigger the cam you run the higher it'll have to rev to make power.

For a roots I would run a cam with 112-114 lobe.

For a street car in a 402 I would maybe run something like 236/244 with .600-.620 lift on a 112 lobe.
