Stroker specific cams (Part 2) cam reveal

Yeah, Schubeck lifters....they seemed to go quiet (as a company). My guess is it was a sound idea on paper but probably required very tight manufacturing and assembly tolerances that were hard to actually achieve. If there is no rolling, only sliding, the need for precision is much greater.

I haven't studied roller lifters too much lately but the most expensive ones seem to be using a wheel with no needle bearings...a 'plain' bushing instead. I looked at some but they were well over $1200 for a set. Makes sense though, as the contact area is much greater with a bushing. I think it was Crower or Isky....you buy their best lifter $$$ then option up $$ for the bushings.

I don't know specifics on what the SBC/SBM guys are using...they tend to keep the details pretty 'need to know'. Some of them run a big diameter wheel that is only about 1/4" wide, even. I also have some friends who are circle track guys....they run their SBC with a modified cam bore and the entire cam is run encased in a 'tube' that only has holes for the lifters to pass through.
