349 CI on the cheap

Yes sir Moper,
Now you are talking a cheap build for the common street guy. I don't understand why the red line would be 5500 though...Can you explain...We have twisted these 360 cranks in the upper 7000 range without a problem or would it be based on the mains being turned down...Maybe the cam you picked out?...Anyway, would like to hear your input...Thanks, Lee
