Thanks for everyone's good advice. My 16 year old son and I installed and broke in the Lunati Voodoo 700 cam (207/213 @.050) on my 74 Lemans. Used fresh set of #47 Heads (checked in at 84cc by local machine shop) w/ new Crower 68404 springs on a previously rebuilt bottom end (3.90 bore/.030 over) w new 60 lb Melling oil pump. Compression is 8.6:1 with Felpro gasket w stock pistons about 15 in the hole.

It is night and day from prior peanut stick #537441 camshaft. Now it smokes tires off the line, pulls hard from idle to about 3600rpm w/ stock converter and the stock 3.08 open rear. Feels like car has about 75-100 more horsepower on my butt dyno. These cams are magic.

Question, my son wants to put in 1.65 Harland Sharp rockers "for a little more top end" - currently it's out of breath at about 4200 now....but pulls fine to 4500 to chirp tires into 2d gear.

Heads did NOT get elongated pushrod holes but I've heard that based on specs of camshaft being small, it should work? Means my lift will go up 10% from .437 and .455 (becomes .477 and .500 lift). What do you guys think?
