The Mancini brand rockers are nice pieces. Same as Harland Sharp minus the bearing.

Early on, we sold most of the value priced rockers on the market including Cat, Proform, Procomp and a few others, and we agree, the quality left a lot to be desired. We wanted to offer something better, but without breaking the bank.

In 2006, we got together with an established manufacturer, and went over every detail of the extrusions, materials, heat treating, etc. Towards the end of 2007, we released our 200-1045 (1.5 ratio) and 200-1046 (1.6 ratio) rocker arms and we've had great luck with them.

As you can see in the attached picture, (which is a screenshot directly from our order management system,) we've sold 1599 sets of the 1.5 version, and in the 6.5 years they've been on the market, 15 of them have been returned. Of those 15, probably half were from people who had gone a different direction with their build, switched out 1.5's for 1.6's, etc, not necessarily people who had any problems. The failure rate is incredibly low on these, as a percentage of how many we've sold.

So, if you are looking for a very nice full roller set at a great price, give these a look. We've had great luck with them and they are one of our most popular parts.

This question has to be asked......

Your store policy states returns are only allowed on brand new Un-Used parts....so is your ratio of sales to returns relevant concerning the quality or failure rate ?

I am sure most wanna believe these are good safe rockers to use....unfortunately every post about them gets muddied up by people that say they "heard" bad things...or guys that refuse to believe any rockers that cost less than $500 are any good....but rarely from people that have actually used them.

I'd feel more comfortable using a set of Crane or Isky ductile iron rockers before using some cheap roller rockers with low-quality bearings and adjusters. I had a set of cheapies trash a bearing and lock the oil pump on my buddies 440. You get what you pay for.

---

WINNER ... I was just going to post this when I saw this thread again. don't forget the roller wheel axle being too hard and breaking allowing the rocker body to pop the valve locks loose and the valve dropping into the cylinder ... but hey at least the company selling the budget rockers will replace the faulty rocker for you ...

Which of your engines did this happen on ? I never knew you actually had an engine that ran in the 15 years you've been here...

Got any pics ? Did you return it for a refund/replacement ?

I am surprised you bought 440source parts to begin with...

Interesting.

As we said earlier, we just thought it might be helpful to post our experiences, and let everyone form their own opinion based on actual facts and numbers.

Looking at the numbers, we've sold roughly 1600 sets over 6.5 years. With about 250 business days in a year, that's about 1 set per day, every business day of every year, for 6.5 years straight. And that doesn't even include other ratios and other offset versions which we sell, it's just this one specific part number.

Is it likely that if these were having the failure rate which is being suggested here, that those types of sales would continue for 6.5 years?

If peoples engines were being destroyed on a regular basis, don't you think we would see droves of angry people coming onto this and other forums telling of their actual experiences?

Or is it more likely that there are a few internet bullies out there who have a political axe to grind?

People who have never made a single purchase from us in their entire lives, never actually used our parts in their builds or likely even seen them with their own eyes in real life.

Yet they instantly jump on every thread with even the smallest mention of our name, with the obvious intention of fearmongering.

We've been a premium advertiser on Moparts for many years, over which time we've paid many thousands of dollars to help support this site and help pay for the costs which allow this community to continue to flourish.

If someone actually purchases a part, and shares their specific experience, whether good or bad, we are all for that. That's what really makes this place a great community where everyone can genuinely help each other out.

But to allow this political fearmongering to continue for as many years as they have, it really does a disservice to both the community here and the advertisers which support this site and make its continued existence possible.

As we've said, take a look at the numbers and the facts, and make your own judgement calls.

I'll probably get banned ... again ... for this

I am not allowed to post links to other forums because 440source cried to the board owner about me doing that, or I would post up my favorite.

What failure rate is being SUGGESTED?


Nothing is bulletproof, even the hi dollar stuff fails, we see it every weekend in Top fuel dragster and Funny car.

I don't even trust Crane Golds in some apps. , I bought a set to run on a mild sold roller and changed my mind and sold them for something a little stronger.

The reason I posted up what I did , reluctantly , was that not everyone NEEDS roller rockers , adjustable iron rockers will work fine for most, that was my comment and I just expanded on the person I quoted ...

Would I have not gotten dogged if I let out the part about the brittle axles and the exchange ??? If so sorry I brought it up.

And for that I thank 440source. With them coming into the scene I was able to buy and build a 500 CI engine and run 8.60's@155mph in my Daytona years before I would have been able to afford doing so with other products. That assembly made 275 HARD passes till on a freshen job I discovered a cracked block. I have since sold the Crank, rods, and pistons and it is still being beat on to this day. I have a new 512 assembly from you guys and it will eventually be in my Duster after I am done playing with these small-blocks. Are Brandon and Natile still involved with the company? They both seemed like they would go out of their way to make a customer happy.
