Cold air intake construction and mounting?

[jlwdvm]

I recently modified the CAI I made for my 69 firebird LS3 Track/street project. I had the MAF sensor (with honey comb) mounted right in front of the throttle body. It was mounted between a rubber coupler and a rubber 90 degree elbow that then led to the air cleaner that was located behind the drivers light. The steel tube was bolted to the inner fender for support. There was plenty of wiggle with this set up due to the 90 rubber elbow. I recently replaced the rubber elbow with steel tubing and placed the MAF in the center of the straight section that leads to the air cleaner. There is still the rubber coupler that attaches the CAI to the throttle body and the tube is still bolted to the inner fender for support. There is some wiggle at the throttle body, but not as much as before. Just wondering how much motor movement I have to allow for with a 570 horse LS and Prothane clam-shell motor mounts?
