Has anyone tried the CAT LRH-350B retrofit roller LIFTERS?

As the topic says, has anyone tried these, or know if they are any good?

For $154.56 from pace, they sure are cheap.

Edited for stupidity: these are lifters not rockers

While they are tremendously cheaper than other retrofit kits, and I think we can assume where they are made, my question is this: should adding a bar to link two lifters together double, or even triple the price of the lifters alone?

While we are on roller lifters does anyone have the part number for 16 factory lifters? I can find the part number for a single lifter 2nd design. I can find the part number for the kit which I don't need the extra pieces also 2nd design.

Pace is out of stock of these for an indefinite period of time.

Apparently there is a supply problem. I was going to take a shot and see what they looked like.

One time I was looking for product info on CAT stuff and I was given a number for one of their reps. When I tried talking to the guy he barely spoke english.
I started having flashbacks to the time I bought a Chinese screwdriver set and they looked nice, but the tips got chewed up after like 3 uses.
I still have them to this day. I use them for opening paint cans.
At least they were cheap.
I've decided that I'd let someone else be the guy who road tests CAT parts.
On a positive note, the stores that sell CAT rods and cranks say they have a good record. So apparently Chinese metallurgy has made some progress since I bought those screwdrivers.
But I'm still hesitant about things like roller bearings.

Some factory hyd roller lifters from Autocenter were $120/set, the last time I checked.

Well then be worried because you may own a car or two with chinese parts in it already.

http://www.china.org.cn/english/BAT/121037.htm

Heres the kicker

GM expects to boost parts purchases in China to US$4 billion in 2009 from US$200 million in 2003, according to Merrill Lynch, while Ford expects annual purchases in China to reach US$6 billion by 2010, or 7-10 percent of its global requirements. Chinese exporters mainly make components for the aftermarket but are increasingly eager to enter into the higher-end original equipment-manufacturing (OEM) sector.
How are all those Eagle and Scat cranks and rods holding up since they are chinese too.

You make a good point because they do sell oem lifters with the cross bar and they are nowhere near the price of retro lifters. Proves that this is just a way to market on something.

These are on ebay. I didnt see any part # for the big block version like these in the Cat catalog. Funny because I have seen other manufactures sell retro roller lifters for both small block and big block with same dimensions. Im not to faniliar with big block lifter dimensions.

I think what they're selling probably resembles the second picture, but it looks like they snatched that image from Summit, so who knows what the actual lifters they're selling look like.
