Keeping with 1.5s, with no jump in lift against a 068 is the Melling SPC-3 (744). It does not have the dwell over the nose of the old 744 cam, and doesn’t require extra spring pressure over a Melling SPC-7 (068).
Lee on here has the biggest cam I have seen successfully using press in studs, is in a 455. IRC…about .445” lift and 222*@.050 intake, just over .43” lift and 240* ish on the exhaust.
