L-79 '66 Novas... Viable?

The issues to consider about this engine combination:

1) There really is no compression advantage over the 275hp engine when both are blueprinted.
2) The heads do not flow significantly better with the big valves (2.02 & 1.60) over the small valves (1.94 & 1.50).
3) The original intake and small Holley carb do not flow any better than the Qjet setup.
4) With the current camshaft rule, there is not that much to be gained with the camshaft lift and stock heads.

It does offer some advantages over the 275hp engine, but not a huge amount.

MHO backed up by some observed data.
