How Would You Build This Stroker?

What classes do you plan on running ??
What do the rules allow you to do??
Any class that allows the engines your are talking about are probably full out race cars. Or racing vipers and vettes or better. That's why when I was gonna race my Cuda on road course I was gonna try to build a 400 plus hp 273 cause starting with a 340/360 would put me up against vipers and vette.
