Scat 5.7 Connecting Rods

What are the opinions of a Scat 5.7 Connecting Rod for a Super Stock application?
Thanks.

They may be fine, but I'd buy Manley's. Its a peace of mind thing.... spend it once, ya know. My original engine builder, convinced me, and I'm glad he did.

I better go find some wood to knock on , now that I said that......

You get what you pay for in most cases.
Any of them can fail. I pulled the eye out of a Manley connecting rod back in the 1990's. Manley did give me a new full set of rods but I still lost a block and a couple of pistons and cam in the deal.
My 2 Cents

yup...no matter what you buy, **** happens. I've seen them all fail...but if you check them when you get them completely/ big end / small end/ length/ Mag, you might ward off some problems...would'nt belive what I've seen in the past 35 years from all of them...

So true Bub...
Had a customer want to supply his own parts for a BB SS engine. He furnished all the parts. He did get a name rod, but they were out of parallel big end to little end about .006.
Try to explain that when checking the deck height. You have to check & recheck any brand.

Have a nice day

No Ed your not missing anything...properly prepared stock rod are just fine to a point. Piston weight and RPM will take a toll on any connecting rod...

All aftermarket rods are made in China. I believe Howards are the only ones left in USA. Ask Manley they will tell you the same.

I have used Scat rods in my bracket engine for years, and now my Super Stock engine. Never a problem. Wesley got them approved for me. I had to donate a sample rod. That is why Scat is listed. Wesley submitted it for me at the end of last summer.

I have had 2 460 ford motors ruined with eagle rods . they snapped in the middle of the rod.
I launched these motors at 1k rpm shifted at 5500 went thru traps at 6400.
both had less than 10 passes. I found out eagle is a chineese rod.. Same as scat
Never again!!!

They are both from China, but the Scat stuff is machined here. The engine builders I have talked to won't use Eagle. I know several that do use Scat. One uses them in all his circle track sbc engines and says he has never had a rod or crank failure. They get a lot of run time around 8000 RPM. I'm not easy on my stuff, and have no problems with the Scat rods.

Probably break one now that I've said that. <G>
