Is this a pump gas street motor? If so you will probably have detonation problems on todays pump swill with that much compression
As far as the cam I would look for a solid lifter flat tappet grind with as much lift you can get with between 245 to 260 degrees duration at .050 with the symmetrical lobes and maybe a little more duration(5 to 10 degrees) on the exhaust lobes and have it ground on 105 to 108 lobe separation angles and install it with between 3 to 6 degrees advance on the intake lobes
As far as that clone M.W. intake for stock type 440 heads I don't know anyone who has used them and like them
I'm a little bias on M.W. cars and motors due to owning and racing several of them, lucky me
If I was advising your uncle I would tell him to run a six pack intake and carbs with 9.5 to 1 compression just to make some of the purist mad
