Hydraulic Roller Lifters

I have a customer wanting to a 460 with hyd. roller cam set up. What is the best lifter to use? I have ran almost every type lifter in SBF and SBC/LS engines with no problems. Never done a BBF with hyd. roller. Thanks

We did it in EMC and it worked fine

The lifters from "Johnson" Specialty Engine Components, (not hi-lift) are the best I have seen and used.
Most people just won't pay their price.

A stud mounted rocker arm valve train will not live very long with hydraulic roller lifters however, a "shaft type" or "Bolt Down" valve train seems to work fine.

Thanks. What exactly will fail with a stud rocker? Going to use aluminum scj heads. This is mainly a street cruiser may see 5800-6000 on a very limited basis.

Usually the valve stem or valve guide or both because of the side wiping motion of the rocker arm across the tip.  
Limited run time engines won't matter.

Why would a stud mounted rocker wear any different on the valve tip or guide in a Hyd roller cam application than in a Hyd flat tappet engine?

Pushrod angularity and rocker arm motion at the valve tip.
As I said, they will work OK if it is not a high mileage street engine.

High mileage? You mean 250k factory stuff? Or 10k race engine?

The guides and/or valve stems will usually show a lot of wear after about 25,000 street miles or at least a few years as a drag race only engine.

Install a solid roller, the engine will thank you
