Re: 350 Performance Question
With that cam, I'm guessing it is going to be a mellow idle with the 350. Is that a thumper cam? If so, I'm not sure how the idle is on those.
What is the rpm range that cam is speced for? For trucks, I usually try to get a cam that produces power in the lower rpm range. I think my cam is speced for 1500-5500 rpm range.

Re: 350 Performance Question
I'd go with a standard Performer or Performer EPS intake. Should make better low-end power and throttle response. I doubt you'll be turning much over 5500 with it anyway.
