IMHO, you would be better of using a fairly mild 440 big block for what your stated needs are.
The problem with this though is that you would have to change a lot of things to big block parts like headers, transmission, motor mounts, engine brackets, etc.
In the long run, you would be better off and it would clear the hood easily if you don't go wild on the intake height.
However, you would have to change your user name though...lol
