Soooo, 500 cube small block Mopar is possible, and yet, I have never heard of anyone building one! Had I known this years ago, the engine in my Cuda would probably be different. Visions of P5 Hemi heads and 500 cubes come to mind....

My only question after seeing this post is why has nobody ever built one before now? Why is this all of a sudden common knowledge, yet I have never heard or seen anything even close to that in a sbm before now.
