Also, you will need a LOT of compression to make that cam work - pistons A. H. A. P (Dome as high as possible), small chambers, etc.
I had a '66 El Camino my stepson wanted to put a long cam in; a 283. It was a DISMAL failure, ate spark plugs, never could get it jetted right. It also ate several turbo 350 transmissions.
I would be real surprised if you weren't a lot happier with a smaller cam (assuming this is not in some kind of race car)
