I'm well aware of the hydraulic lifter pandemic and that's why I want a flat tappet mechanical setup. I assume their not the same since they are just a fraction of all lifters and are hopefully not made in China.
Roller cam is not an option since I don't have the funds. On top of that it seems like the bad manufacturing/ quality control pandemic is spreading to rollers too. Lots of reports of failing roller lifters on the net.
Having an engine built on the other side is not really on my budget. There are good engine builders here in Sweden too but, again, it's out of my budget.
