For Sale : Carrillo Rods For Sale

[NateD4]

I have a set of Carrillo H beam rods for sale that fit the 2.8/3.1/3.4/3.5 cranks. Rod length is 5.916" with a .906" wrist pin bore.

I'm asking $680 for them. They are brand new and have never been run and have the super high strength SPS CARR 7/16" Rod bolts.

[NateD4]

Rods are listed on eBay again if anyone is interested.

[mfuller]

Too bad they aren't stock length, or I might be all over them.
GLWS.

[unchained01]

Exactly that's why I didn't buy them months ago

[NateD4]

I get that. If my crank wasn't so odd I'd be using them.

What I don't get is that if you are running a rod like this it makes no sense to not run forged pistons... Which unless I'm mistaken means custom pistons anyway. Are there stock forged pistons available?

Am I missing something here?

[ForcedFirebird]

No, but you have to pay an up-charge if the manufacturer hasn't made that particular combination. We have gone through that several times when changing pin height etc.

[NateD4]

Hmm... not sure what brand you are referring to but the quote I got from Diamond and JE didn't appear to include any surcharge that was cost prohibitive.

If anyone is interested in the rods though let me know. I presume if you are going to the expense to put a good set of rods in, the cost of the pistons is either a given or a non issue.

[ForcedFirebird]

Removed.

[NateD4]

Technically moving the pin height is a custom design. That is IF they are doing a stress calculation on them to make sure things work right. I would hope both JE and Diamond do this on every set of pistons.

I have a set of Carrillo H beam rods for sale that fit the 2.8/3.1/3.4/3.5 cranks. Rod length is 5.916" with a .906" wrist pin bore.

3500 cranks have a different rod bore than a 3400 and older crank. What is the bore diameter of these rods? If I am not mistaken, and these are for the older smaller journal 2.0 inch cranks, these will not fit a 3500 crank unless you turn down the crank journals.

So do these fit the 3400 crank or the 3500 crank?

For sale is a new, unused set of Carrillo custom connecting rods for a GM 60 degree V6. These are the proper width for a 60 degree V6. These rods will fit a stock 2.8L, 3.1L, 3100, 3.4L, 3400 GM 60 degree V6. They will also fit a 3500 and 3900 with crankshaft modifications. They should also fit a 3.4 DOH or 3.4 TDC engine.

The bolts on these are genuine SPS CARR cap screws. They are a multiphase steel with a tensile rating to 250,000 PSI (or 250 KSI). This is a top notch set of rods good for well over 600 HP.

They will require a set of custom pistons. CP-Carrillo can make the pistons to match these rods.

Rod length is 5.916"
Pin Bore: .906" (23mm)
Small End Width: 1.065"
Big End Width: .855"
Big End Bore: 2.125" (without bearing shell)
Big End Bore is for a 2.000" journal size.

Total Weight: 706g
Small End Weight: 204g
Big End Weight: 502g

I intended these for a build I was planning however the new crankshaft I have uses different rods, therefore I have no use for these parts.

I can also include a single performance bearing shell, and can order 5 more to fill the set out for additional cost.

Message me with any additional questions.

for a 3400 crank.. gotcha. Thanks

[NateD4]

I have a 3900 crank. I'd talk to your local machinist about grinding the journals to 2.000"; the cost may be worth it.

The 3.9 Crank has 2.25" journal sizes. Which from what I can tell is a complete odd ball size.
Or another option would be to buy a set of BBC light weight rods (whatever rod is about the same weight as a SBC heavy rod) and have them narrowed. Then grind the crank to 2.220" Journal, have it nitrided. You then may need narrowed BBC bearings to fit.

Alternatively you could always have your local machine shop bore .050" out of the rod and re-establish the bearing tang slots to the proper depth and alignment on a BBC 2.220" Rod Journal diameter and run stock GM 3.9L Bearings (which I believe are bi-metal from the looks of them). Not a bad option but not bolt up.

____________________________________


From my point of view you can't buy a set of rods like this for this kind of money. A set of Small Block Chevy rods will run you $300-$500 depending on brand and type (I-beam vs H-beam) and are made from overseas steel (to my knowledge no one sells US made steel rods in that price range).

Then if you get them you'll have to have the crank journals widened to .946" to .948" or have the rods narrowed. If you want similar bolts to the SPS CARR you'll have to request or buy additionally SPS Custom 625+ rod bolts.

Most of the rod makers I called wont resize the rods for you with the new bolts. They also won't produce them with upgraded bolts.

The total cost with new bolts, resizing and narrowing puts the rods around $450 to $700 with ARP 2000 bolts (or similar) or $650 to $1000 with ARP Custom 625+ Bolts.

The set of rods I replaced the Carrillos with (simply due to rod width) has similar spec bolts and is rated for well over 8,000 RPM and good for more than 600 turbocharged HP. The Carrillos are rated similarly perhaps a bit higher.

Carrillo charges about $300-$350/rod these days for a complete custom rod made from their steel alloy (similar to 4340). To my knowledge the only other makers of full custom rods are Arrow, Pankl, & Pauter, and Molnar Technologies (there might be one or two more that I can't think of at the moment).

If you want to check the options for other off the shelf brands take a look at:
(all sell a 'bargain' rod made from either overseas forgings or made entirely over seas, my research indicates there are 3 maybe 4 plants making all the rods for the below companies)

Crower
Manley
Scat
Eagle
Lunati
Callies
Summit Racing


I did a quick search on Summit Racing for H beam rods similar to this set of Carrillo and it looks like a set of Eagle or Scat rods run between $400 and $460 and come with ARP 2000 material (8740 rated at 200KSI). If you cost out new bolts and resizing the ends for them as well as narrowing them I'll bet you'll be tacking another $200-$300 onto the price.

For further reference ARP L19 alloy are 220KSI and a set ( sells for @ $149 to fit Eagle rods.

Jegs Sells ARP Custom 625+ Fasteners for @ $220-$260. However I didn't find any that directly match to any of the rods listed above.

Note: ARP Custom 625+ is 270KSI+, while SPS CARR is 260KSI

While checking into the above I realized the 3.8L buick rods have a 2.249" Journal size. Which is in the size window of the 3.5L/3.9L crank. The kicker is 1) rod length it appears not much is available below 5.967", 2) Big end width is .845" on 3.8L, while my LZG crank measures .867" wide and the rods .858" wide.

It might be workable but will still require custom pistons and cost about the same for the rods as the Carrillos. The big question is how much it costs to grind the crank down to 2.00" or 2.100", nitride it then finish the grind and add the oil hole chamfers that need to be there.
