65 center oiler block so it isn't drilled to the lifters.
Single pattern cam 242 at .50 102 intake 109 exhaust.
I’d be at 236/246 at .050”, 109 LSA, 107 ICL, .580”/.574” gross lift. I’d have it ground with 4 deg of lobe taper to help with cam break-in and continued longevity.
With the TFS heads flowing so well, you don’t need as much duration to get to a specified peak.
Bad thing is right now, no one has cast iron cam cores for FEs, so I can’t promise you an ETA. Normally it just takes a few weeks but that has been stretched out.
