So what's the max lift this thing will support?

That's really the deal breaker for me and why I had to ditch the idea of using the factory roller setup on a Gen V BBC and convert it to link bar,...

Any reason why you want to keep an EGR valley pan?

Just thinking out loud but it seems it would be easier and much cheaper to just modify the EGR pan to work with retro lifters rather than...

I've been pushing the 91 pump gas for years here in Arizona, same junk California has. I'm running an 11:1 engine with iron heads fine on it, it likes 36 degrees of timing where it made best power,...

Enough spring pressure to properly control things shouldn't be so far out of whack on a hydraulic roller setup to even worry about roller wear or failure. I think this whole thought process is...

Won't

Most guys here don't even spin their Pontiacs above 5500, and many others don't make power much above that. It's the street section. With a proper spring valve train control is not an...

Paul C just told me Johnson has another batch of hydraulic rollers in stock for Pontiac. He orders directly from Johnson. However they aren't $700 anymore. He told me the price has jumped to...

One thing everyone forgets is those OEM lifters in OEM applications are also running on OEM springs, which are lucky to have seat pressures of 90-100 lbs, and running on OEM lazy lobe cam profiles. ...

Yes the weight of the valve train has a huge affect on spring pressures needed to control it.

If you don't like the Johnsons or don't want to do the lifter bore mod, then why not look at a set of the Comp S lifters? The oil bands are in the correct location and come recommended by Paul K. ...

Might want to contact Paul, I don't think that was the case in the failures he was seeing.

Link bars aren't a deal breaker for me.

I posted earlier I've bought brand new dog bones, spider, and roller lifters from Ford Racing for just $175. So that price seems a bit high, even if it were new.
