Billet cams and lifter supply

Gary Parker · 11-04-2022, 02:22 PM

For those who can't remember back when we used to have to meet overlap and duration with the cam and spring pressures were checked we were still wiping out camshafts. That's why the schubeck lifters were such a hit when they first came out. And now with the cost of today's engines it would be nice to bulletproof them so they do not come apart.

Even if Stock were put back to "Stock", this^^^^^^^^^^^^^^^^^^^^^ will never happen.

I apologize if this comes off a bit standoffish, especially coming from a 19 year old "kid", but there are more ways to control a radical camshaft than throwing heaping amounts of valve spring pressure at it. At least with flat tappet stuff, I don't see why you couldn't build a good stocker engine with, for example, a 150lb on the seat valve spring rule. I know it probably means nothing to the average A,B,C stock racer, but the 6 cylinder engine I built last winter was quite happy with about 100lb on the seat, and that cam is by no means "soft" in any way.
