Oh well then they would have to check valve spring pressures at tear down again. To much work I guess.

Yep ,Terry. Then you wouldn't need weldments added to the pushrod cup on OEM type rockers, only on certain brands.

So what we have is another Super Stock class with a tire size limit and spec cam lift. The heads are "almost" the same....lol.

4 From which manufacturer, Schubeck or Smith?

I've been running/using my Schubek lifters for quite a few years now,never a problem.

I had my first Schubeck failure using the exotic all composite body. It shattered. Had to replace all the bearings and rings. I lost a second engine to a puck coming off. Broke the camshaft and took out two rods and pistons. That was the end of that experiment.
Great idea as long as everything works as advertised. But if it doesn't...

If the shubecks and new shubecks (Smith) aren't viable options what hydraulic SBC lifters you guys recommend ?

Glenn Briglio · 11-21-2009, 08:24 PM

There were many problems with the Schubeck lifters. I've sold about 50 sets of the Smith lifters with zero failures to date. I would like to hear of any problems with the Smith lifters.

Tool steel lifters are sold by Ferrea, Performance Research Incorporated, and Precision Performance Products.
