OK guys I’m trying to sort out my catch can situation on my 383 build

Here is my situation and my question..

I’m running an elite engineering catch can.. I am feeding the dirty side from the driver side valve cover.. around the back of the intake and along the passenger side valve cover to the catch can. My intention is to cap off the back port of the passenger valve cover and provide a fresh air feed to the front port of the passenger valve cover. And of course, naturally run the catch can outlet to the intake manifold port behind the throttle body.

My main question is this. I’m running a fast 102 that has an LS2 throttle body on it.. so there is no positive pressure fresh air port on that throttlebody. From everything I’ve been told and read I should be able to grab fresh air anywhere after the MAF.. and prior to the throttlebody. My my question is, wouldn’t that make it a negative pressure source under throttle and not "feed" the valve cover fresh air? And if so, does that matter for the purpose I’m trying to achieve.

 

This place isn't the hotbed of activity it once was that's for sure
