Just an opinion, but you’ll need some rpm to make power. Still a nice combo with a 4 speed. I’d put something in with a 108 lobe separation since the compression is a bit low. I bet an old isky mega cam would make really good power. They’re on a 108. I ran an old cam dynamics 253/253 525/525 on a 108 in a turbo headed 331 with flat tops years ago and it ran STRONG. 7.70s in the 1/8 mile in a stock bodied 73 z28 with a 4.11 and a 4 speed, and my shifting sucked.
