Total performance, D&D (not D&D Motorsports), and a few others have fox motor plates.
I think mine is a D&D, but hell its been a few years since I bought it. Another thing you definitely want to do is spend the $250 and get a tubular K-member as it will give even more room.
BTW, what headers are you going with?
www.corral.net has a good big block forum and you will find all that you need there.

Do you own a Torch Red FRC and tremble every time you drive under I75 on Hwy 60 and look in your rearview mirror? If so you are suffering from what is known as Cobraphobia.
