Would you trust these?

While browsing eBay I found these roller rockers... http://cgi.ebay.com/ebaymotors/SBC-CHEVY-STAINLESS-ROLLER-ROCKERS-1-52-3-8-23021_W0QQcmdZViewItemQQcategoryZ33624QQihZ016QQit emZ260235603553QQrdZ1QQsspagenameZWDVW

Skipwhite is the seller. I have only heard good things about skipwhite but would you trust these? It seems they are kinda cheap...:confused:

I've been watching these too. Skip has a lot of interesting stuff, just don't know how good they are.

I am seriously considering them... If they are decent, I could install a complete 260H kit from Comp Cams, buy all the gaskets, get a one-piece oil pan gasket, and get roller rockers for under $500.:)

My main concern with these Chinese products is consistant quality. They are capable of turning out a good product, but they are known for cutting corners when QC is not looking. It is very possible to get a good set, but I think it is luck of the draw. The more I think about it, I wouldn't buy something that will take out my engine if it fails.

[supernovanator]

Forgive my rookie question, but what on these would fail?:o And is there a way to check quality before installation?

[tnblkc230wz]

The bearings, roller, roller pin, body, inaccurate ratio, not correctly centered. You name it.

The thing I like about skip white is that most of the parts he sells on ebay he uses personally. Yes they are most likely chinese but they are capable of making very usable parts. I haven't run them personally but I think they would be ok to run. If you get a bad batch skip will replace them. His customer service is second to none. Give them a call and ask them if they have had any problems with them. He is a pretty straight forward guy.

I could also try to contact customers in his feedback to see how well they held up.:) In fact I shall do that right now.:)

A serious stud mounted rocker arm would be built for a 7/16" stud.

If they pay as much attention to the details of the manufacturing process as they do to the details of the spelling in their auctions, I'd pass.

Maybe his parts and service are OK, but buyer beware after that.

Before everyone jumps the band wagon here think about the way today's industry is setup. I've been growing up in a family of business owners. The cost of bulk goods is WAY less then the cost of individual goods.

To throw a bit of a curve ball into the thread check your summit catalogues under roller rockers. You'll notice they have an almost identical product sold by Comp Cams only made in chrome molly. I bought a set of Skip's race pushrods and when I took them to my engine builder he asked where the hell I got comp pushrods for $40. He compared them to a set of comp cams pushrods he had on stock and they were exactly the same.

Everyone said that Skip's cylinder heads are made in china to. Turns out they are actually forged in the united states and assembled in Skip's machine shop.

I haven't had too good of luck getting the right pushrods for my motor(The factory first sent me 14, then I found out those 14 were for a roller motor) but their customer service has been amazing. If something isn't right they correct it at their cost without any questions!

I have no problem ordering from them.

I am not sure. The advertisement does say they are Wysco brand, whoever those people are... I have not found information regarding them online yet. I DO want to trust Skipwhite seeing his reputation here and on ebay, but at the same time I would not like to risk my motor at all. I messaged 5 or 6 people last night who had bought these, either in 3/8" or 7/16". I just got responses from 3 of them who said there were no flaws whatsoever, they checked every inch of them, etc... who knows.

I did, however, find some on ebay from other sellers, but they were claimed to be other brands. One brand was "Condor," which is a motorcycle performance parts manufacturer based in China. I am weary of this.

I am not sure of the brands and all that mixed up mess, but if I was uncertain about Skipwhite's at all, I would buy the Summit ones.:yes: Perhaps there is a way to test these before installation?

There are many rocker arm products made by many fine companies, but the most advanced and leading edge "innovation" that matters in rocker arm valve train was not accomplished by any of the "big names." Instead, the most fundamental concepts of rocker arm geometry went undiscovered for many years, until MID-LIFT was developed in 1973 for an engine few people cared about. Jim Miller Patented this concept in 1982, and for many years the top valve train companies tried to ignore it; some even denounced it. Today, it is the only method accepted by both Chrysler and Chevrolet's performance engineers.

MILLER ENGINEERING INC (MEI), a Florida "S" corporation, was established in 1993 for exclusively designing the most precise geometry, strongest, light weight roller tip aluminum (and titanium) rocker arms available anywhere for select classes of professional racing. Totally overseen by the founder of the only US Patent ever issued for rocker arm geometry, Miller Engineering occupies a modest 2,000sf of offices and an additional 8,000sf manufacturing facility in Pompano Beach, Florida. Multiple 4 and 5 axis Kitamura CNC mills and Mori-Seiki lathes are driven by state-of-the-art software and on site QC inspection.

Recently, some of these well advertised companies have begun to change their rocker arm designs, trying to adapt to this "better geometry." But THIS is where MID-LIFT began, and has continued to evolve with additional Patents and more Patents Pending. MEI is dedicated through two separate product groups to bring real innovation and real information to the most important customer: THE ENGINE BUILDER.

For the select (but growing) list of engines we make MID-LIFT rocker arms for, you will not find a better rocker arm anywhere. MEI is the ultimate performer, and PVS is the ultimate value. MID-LIFT sets the standard that has long been a secret to advanced valve train development. We believe this web site will also set a new standard for valve train (and other) information that you won't find anywhere else. We continue to provide consultation services through both this web site and in person, as we have for numerous NASCAR teams in the past.

Those roller rockers above are only roller tip rockers. I've heard they "drag" a lot more then the full roller versions available. Something worth checking into.
