pulley swap and re-tune gets you to 700+ hp. Beyond that, head porting and a cam swap gets you another 50-60 hp or so. Charley recently did the pulley and tuning on his stock LS9 69 Camaro and is very happy with the difference, very noticeable.

That but switch the meth to E85, then add different fuel system and lines you'll go into the 4 digits rear wheel on a mustang dyno.
