JMO but with a 416 in your car its the same as a stock car.. big deal that it has a 4" crank... if you look at it it still has the number matching engine... I would also keep the interior in it and as stock as possible... with a 416 you can get into the 10s unless its some special tank(super heavy).. thats the cheapest way to do what you want and still keep the stock look about it
