Stocker flat tappet lifters

FINESPLINE · 01-21-2011, 12:59 PM

Considering the aggresive grinds that are now used in stock, what lifters would be recommended ( solid & hydraulic ) in a chevy. I have read up on the Schubek---Smith Machine style and some tool steel type. Also , what varieties of treatments can be used on the camshaft itself. What experiences can you pass on ? Thanks in advance, John

The most reliable is the tool steel, because, simply put, they don't break, where any ceramic lifter can break, or even shatter. If you're going to run a cast iron core cam, DO NOT use coated lifters. If you're going to run a steel billet cam, then you can run coated lifters. The cam needs to be fully de-burred, and if possible, nitrided.

On a serious stocker effort I would go with a DLC lightweight steel lifter on a polished billet or powdered metal oversized cam core.
