did you see the build in one of the magazines..521CUIN and 820hp on pump gas..
how about the one on GEARZ TV thats going in a Cougar..I think its the same engine or one that was built like it...
they also say it can be built for 10k...bet the lower end dont stay together on that on...I figure around 20k (I figured one up too at 15k)will build a nice stout pump gasser..
