Cam Selection 360
Thanks for suggestions guys,
Lifters were kept in their orientation just in case. I even quickly built a little wooden jig to do so, thinking I'd be reusing parts:
But it after it was disassembled, it was clear the lifters and cam are all worn out. No catastrophic failure, all evenly wore, but lifter faces no longer convex and cam lobe peaks rounded tells me they're at the end of their life and could certainly be a problem down the road.
That said, I can't justify throwing the old stuff back in while the engine is out. It will get replaced.
Regarding ignition timing, I had previously recurved the distributor for approx 12 degrees initial and 35 degrees all in. Seemed to work well. A HUGE upgrade from the factory 1974 spec of 0 degrees initial and 20 all in.
