do they do what their advertised? thewhiz427 says he dosent have a problem with them, so i'm good there. They are advertised for more low-end torque, is it true? i mean has anyone ever done a test or have some facts/opinions? i wanna know, they seem too good to be true on my rebuild/stroker (much later project)
They are for when you have a large camshaft and need to tame it down at an idle to have vacuum for brakes and such. They just bleed off more than standard lifters and will tick like a solid lifter at an idle.
