I bet you could 8.99 in a 3000# f-body with a stock short block for at least a couple few events. The point is, it will live for a while and the genIII's will melt pistons and break rods at half that power. I love the genIII. I'm building one as we speak. I'm just saying, it has a few major things in the lower end that won't let it live stock where an LS can and have lived for a long time.
