Cheapest 6.625 Forged Rods ?
« on: September 20, 2014, 07:15:22 PM »
As of this post time, the cheapest decent forged replacement rods, in a 6.625 length, are the 5140 RPM rods, direct from RPM. If anybody knows of a better price for these rods, or equivalent rods, please post that info on this thread. For a few years, these rods were just about as cheap as resized cast rods with ARP bolts. But the price has risen. :sad: Current price shown is $276.

For this price you might be better off to add a few bucks to it and go with 4340 H-beams.

Or if you got the $$ and would rather buy American, you can go with Crower rods.

Eagle and Scat rods with optional bolt choices are priced between the RPM H-beams and Crower rods.

Oldskool,
Nice find on the RPM International website! I guess it was inevitable that the price on 5140 I-beams would go up- at least forged Poncho cranks are still priced decently.

Ohio Crank has a nice price on their H-Beams which feature 7/16" ARP 2000 Rod Bolts factory installed. I believe $399 for the set?

I just checked their site. The price I see for the 6.625 Pontiac rods is $449. This is probably about the same price as the RPM H-beams with the bolt upgrade. And I think RPM pays the shipping.

That brings up a question. RPM is the supplier of rods to places like Butler and KRE. So are these Ohio Crank rods the same as RPM ?

Boy, I sure wish Ohio Crank offered their street/strip rods in the Pontiac size. They are only $219 and stronger than the 5140 rods. The 6.535 BBC rod is the closest thing they have.  :sad:

Another rod question. CP shows these 5140 Pontiac rods for $243 shipped. I use to think these were the RPM rods. But an engine builder told me that these were either CAT or Scat brand rods(I can't remember now which he said.). So the questions are: What brand are these ? Are they still available ? If so, are they just as good as the RPM rods ?

http://www.competitionproducts.com/5140-I-Beam-Rods-Pontiac-6625-Press-Pin/productinfo/4556/#.VB-XdJRdX0w

The SCAT website shows only H-beam Pontiac rods in either press of floating pin, with the 2000 bolt upgrade available. So is the CP listing just out of date ?

http://www.scatcrankshafts.com/

While I'm on a roll, asking questions, what about these cheaper no-name H-beams ? Are they inferior to say RPM or Eagle ?

http://www.competitionproducts.com/Racing-Series-4340-Steel-H-Beam-Rods-Pontiac-V8-6625/productinfo/6625/#.VB-cVpRdX0w

Many say the cheaper Chinese rods have bad machining, which the machine shop will have to fix before they can be used. All RPM rods are Chinese. Some say that all Chinese rods are bad except Eagle and Scat. Some won't use any Chinese product. Therefore I ask these questions.  :-)

Oldskool,
Even Eagle and Scat use rods and cranks forged in China- to my knowledge only Eagle does it's own machining in house, not sure about Scat. I bet Eagle probably even pays RPM to make sure their rods are on the money, and just repackages them- only a dial indicator will tell you otherwise.

My experience with RPM International products is good- I used to buy their rods and cranks from PPR, when they were open. PPR sent all of the rotating assemblies to a local balance shop- they never noted any out of round condition with the rods or crank journals, nor did L and R Machine in Brea, CA. I'm also betting Ohio Crank also sources their forged cranks from either Scat or PRM, so I see no point in buying a crank from Ohio and paying for shipping when I can drive an hour and pick it up locally from RPM.

WOW - $778 for Crower rods!  Guess I shouldn't be surprised.  I wonder if these are the same as the Crower Sportsman rods from a while ago? I'm pretty set in my ways now and I'd save up longer so that I could use them again, though this is my last project car. As the previous posts note, you have to really do your research these days to sort out the Chinese stuff that various companies sell under different names and numbers. And, of course, the companies in China have no scruples and few legal restrictions.

OK, here's an update on the RPM rods. I just got off the phone with Competition Products. He assures me that both the 5140's and 4340 H-beams are indeed RPM brand. He said they have 2 sets of the 5140's in stock, ready to ship.

SO, that means that as of this post, CP has the best price I can find for both the RPM 6.625 length 5140's and 4340 H-beams.

And here are some H-beams on Ebay which may be the exact same rods, made in the same place.

Qjet,
The quality of Chinese forged rods and rods from RPM has been spot-on for me in the last 6-7 years I have been using their products. I have heard that earlier batches of CAT forged rods weren't so good, as well as some early batches of cast Eagle cranks- I'm sure there are still some of these floating around out there on the secondary market, so buyer beware. The Chinese have been forging metal for over 3000 years, so if you want good metal they know how to make it- but if you also how the Chinese are culturally they are not gonna give away anything for free either. You get what you pay for. Ace Brewer, owner of Pacific Performance Racing, personally went to the Foundry in China where all of the imported rods and cranks are made- he made the deal happen for these parts to be made and that is how they came into the US market. He also used RPM rods and cranks in almost all of his builds when PPR was open, so the parts are proven.

The price on Crower Sportsman rods has come down in recent years too- back in the 90's when they and Carillo were the only game in town as far as forged Pontiac rods are concerned, Crower wanted $1200/set for those gold-plated specials. Now that good, inexpensive forged rods are readily available, Crower had to drop their price.

Thanks for posting that info Geno - I'm sure it will be a help to the members. If you trust them - others should too.  As I get older, I like to pass on things that I've learned, but I must concede that as we get older, some of us forget that times change and younger guys want to try new things - it's how the hobby has always been.  Thinking back, I got a Holley Dbl. pumper soon after they came out - and the old guys at the garage thought I was nuts.  $100 for a carburetor?

Has anyone had any issues with the Wav-Loc bolts? Which sets utilize these bolts?

Had a friend who said they were a royal pain to deal with. Too tight getting off. Ended up reassembling the motor for other reasons. Thought that the caps might have been misaligned somehow...
