There you go. I can build an index (10.90) for around 5000.00 and 7500.00 in my 422 smallblock that would be perfect for (9.90) index. A good running heads up engine will cost you 10's of thousands and then 10's of thousands in the chassis. And lots of testing from what I see around my neck of the woods
