First of all you can put a 318,340 or 360 or even rebuilt the 6 into a hyper pak and then you don't have to keep the hood closed. The last thing I would do is put a chevy into it and when you try to sell it most mopar guys will walk away from it. I know this for a fact after going to car shows most mopar guys if it has a chevy or something else will walk away. So you really limit your market.
