Why would a core for these cost any more than any other billet core, they’re all just a round bar of steel !!!
I'll take a w.a.g. here (and am fully expecting to be corrected by others in the know)...
- Common steel roller cams are ground on less expensive rough-ground cores which are limited as to both LSA and firing order options
- Stepping up to something completely custom will incur a price increase for a higher quality core, as well as additional labor for machining a UGL (unground lobe) core
The cost for a "basic" roller from someone one like COMP is maybe $400; get something from Jones Cams that could be basically the same thing on a higher quality rough-ground core and you're over $500. Go the next step to go "full custom" on firing order, etc., where you have to start with a UGL... all I can presume is it's "more", but don't know how much "more".
