I have to use a scoop mount bracket under the throttle body to mount my hood scoop and air pan. The bracket I have been using has a 4 hole Holley pattern in it. My question is should I open this bracket up to open pattern design? I can see where the 4 hole pattern is a restriction compared to the open design. However, I wonder it the 4 hole design could have venturi effect under the 4" throttle body. What are your thoughts? Jim
