Unported head quickness?

stock 5.7 hemi with modman intake. Enderle bird catcher injector and a hughes aftermarket cam and lifters. running alcohol in my 3000lb 67 barracuda. ran 10.71

How can it be a stock 5.7 if you put a Hugh’s cam, enderle injection, and on alcohol. You guys don’t even understand STOCK. Lol
