If you are looking for a quality peice yes they will hold up where stock or welded rods will fail.
They are machined well (not that my opinion means anything) and are helpfull for stroker and rpm motors need to be able to handle the g loads.
They also help clear things because of the smaller size. However anyone with a little know how and a CNC VMC can cut blanks from 4340 steel.
I think they are over priced. I would do an internet search for "custom billet connecting rods" and see what turns up.

I think Eagle, Oliver and Crower all make rods. You might get a better price going to a company that is able to deliver the same product without the x months wait period. Its not rocket science. The just draw it out in a cad program and send to the vmc which converts it to x y z travels and tada, you have a blank. Then they bore rod bolt holes and split it to make a cap then size them on a rod machine and it doesn't take a 20 dollar an hour guy to do it.

Right or wrong that's my opinion and i'm sticking to it.

PROGRAMING THE TOOL PATH FOR A CONNECTING ROD USING ABSOLUTE COORDINATES IS A MATHMATICAL NIGHT MARE. WHEN YOU HAVE INTERSECTING AND TANGENT RADI. YOU HAD BETTER BE A MATH PROFESSOR. THE CAD CAM MAKES IT EASY AND LETS YOU SEE WHAT EFFECT DIFFERENT RAD SIZES WILL PRODUCE. THIS WAY YOU CAN SEE THE ROD BEFORE YOU MAKE THE FIRST CHIP. I HAVE 2 MORI SEKI VMC 'S AND ONE HORIZONAL AND 5 MORI CNC LATHES AND A CAD CAM SYSTEM( TECH-SOFT ) WITH 2 1/2 D CAPABILITY. KEYING IN A PROGRAM ON A LATHE IS A LOT EASIER THAN A MILL ,TAKE MY WORD FOR IT, IF YOU DON'T HAVE A CAD CAM SYSTEM YOU WOULD BE WELL ADVISED TO SEEK THE HELP OF SOMEONE WHO HAS ACCESS TO ONE AND MAYBE THEY COULD HELP YOU GENERATE A PROGRAM THAT WILL PRODUCE THE ROD YOU NEED. AND BY THE WAY IT WILL TAKE A $20.00 AN HOUR MAN AT THE LEAST. GRANTED IT IS NOT ROCKET SCIENCE BUT IS SCIENCE JUST THE SAME AND REQUIRES A LOT OF TRAINING AND EXPERIENCE. GOOD LUCK DANNY H.

My intenetion was to have it programmed which anyone can learn then anyone can indicate a peice of steel in a vmc and watch it cut once you are shown how. Some of the other machining process would take experience. A friend of mine that runs a fadal every day says a kid could do it if they were shown how. I don't know for sure but i suspect most anyone could learn a few simple steps without being a professional.

What gets me is 8 eagle racing rods don't cost half as much as 6 special rods.

Cunningham rods are very good. From what I have herd, prices for a WC were around $1000 a set.

You will be pleased with any of the above rods. As for what it takes to make a good set of rods, forget the "billet" and go with a forging. I also have 4 VMC's with full 4 axis capability, cnc waterjet for blanking, and master-cam, but learned my trade sinking forging dies with manual machines, all of it requires brains, but making dies the old way was a skill no CNC button pusher(like my employees) will ever have, and the strength of a forged 4340 or titanium rod will never be matched by a billet rod.
