Carb

I was asking should I buy a 500 CFM or larger?Also I would like to replace my OEM roller cam for a RV style roller cam.If there is such a RV roller cam.Most roller cams seem extreme requiring spring change ect.

I have had two of these engines although they were 360's.The best cam for them is the Comp HR264-12.It has 210/220 duration and .480/.480 lift on a 112 lsa.These things pull like a freight train!!

600 will be fine.Engines only use what they need that is why Qjets were 750-800 cfm even on 305's.I would put an Edelbrock 1406 on it and call it done.
