So i decided to try to run v8r headers with the monster subframe but had a little interferance in a couple of spots. I made up these plates to move the motor back an inch to fix the clearance. 3/4" would have been better. I had to clearance to top of the tunnel with the additional setback. On the plus side, since i'm running f-body accessories, the extra inch up front means i wont have to comprimise on my fans/radiator placement.
