I am looking at H beam connecting rods for my 454 chevy motor. Demotor performance has H-beam rods part # DMTRM714L on ebay for a discounted price. This California based ebay merchant has other internal engine parts for which they show the brand name- Scat, Eagle, etc., but for these con rods there is no brand. I suspect they are Chinese. This does not necessarily disqualify them, since a lot of the old time vendors are now forced to use Chinese parts to stay competitive. Have any of you used these con rods? I have sent a question to the vendor, but have not heard back from them. TIA

We will resolve it for you. Thanks. Any inquiry, please feel free to contact me. Have a nice day!
So I guess this answers it for me. Poorly constructed sentence structure shows the writer is Chinese and they will not tell what brand the con rods are, so they are probably no-name Chinese knock-offs. But......they will stand behind me if a broken rod goes through the side of the block. That make me feel a lot better.
I wouldn't trust them with that response. A lot of forging has gone over to China these days. Some is good quality though. The Scat Pro Comp rods are really nice. I put a set of I beams in the 467 I am building. The machine work on them is beautiful.
please contact immediately if have problem with part leaving engine at high speed. have many complaint this days about engines misplacing connecting rods.
is completely normal and we will replace any parts that leave in such a manner until some that do not found such a way.
Thats the issue right there. I have no problem with a company that wants to make a poor/cheap alternative product if they would just be up front about it.
What I have an issue with in the business sense the companies are pulling sinister and cunning tactics, as disguising themselves as other products (counterfeit), repackaging (same part for ten different prices/labels), US marketing (Is it made in the USA? Or just imported to the USA?) and use your imagination.

Yeah, I'm looking at either Scat or Eagle. I'd like to get Callies or one of the high end brands, but it is probably overkill for my engine which will have less than 550 hp and they cost a small fortune.
I have motors with Manley H beam bushed rods and ARP bolts. They don't fail and you never have to worry about them. You buy nice forged pistons with spiral lock floating pins all of them are sub gram in weight between all of the parts
balancing good crankshaft doesn't ever have to add heavy metal just a few drilling the throws ends
There`s two things in life you can not skimp on.
one is something you buy your girl friend/ wife Or both if your lucky
the other
Quality Parts for your engine
and buy form someone who will be there tomorrow when you go back to ask a question.
Considering you can get new Scat I beams for under $300, I can't see trying to go any cheaper then that.... Hell you can't even machine GM rods with new bolts for that.
I got sucked in initially by the low price-$199.99- and was hoping the rods were a name brand direct from the mfgr to lower the cost.
I can't think of an engine part more vital than the rods, so why chance it? Some Chinese stuff is OK and is often fair to good quality, if you can tolerate the poorly translated instructions, such as these on the battery charger for a tactical LED flashlight I recently bought.

Having used stuff from both companies I would stick with Scat. I have had some issues with Eagle stuff over the years. Most recently a crankshaft that had a cam cut off so it hit the pistons.
The Scat rods are forged in China but Scat inspects and machines them in their manufacturing shop in the USA. I think they are an excellent buy and have never had a problem with them.

long term it’ll work out far cheaper if the rods stay inside the block.
Scat and some decent rod bolts.
Rod bolts stretching/bearing spinning is the most common biggest failures i’ve had.
Had a piston crack on a 351 cleveland shortly followed by the rod appearing outside.
same thing with heads, several guys in the US are now buying cheap cylinder heads, and machining them to make excellent heads after a dozen-or-so hours, the bulk is good, you just need to put the finishing touches on it.
Say what you want about Harbor Freight, you take one of their Earthquake 1/2 air guns apart, polish a few parts of the air chambers and chamfer the ports to the vanes and you have a very nasty little impact with minimal cost. Once again, the bulk of the work is done, you just have to finish it up.

Naramlee - Same idea happened regarding the heads. I had purchased Pro-Comp heads for my 496 build but couldn't get the pattern good enough on the valve stems regarding geometry. I gave them to my high school friend in BC who owns a speed shop to have and play with. I bought his Edlebrock, already worked over heads.
He took, as he says " A lot of hours and a ton of material out of them" because they ended up surprisingly being a good base to work with and provided a lot of wiggle room with options.

Chad Speier is doing the same thing, with some rather crazy results, my 355 heads flowed over 320 @ just .600 and the torque is more what you'd expect outa of a 383, only without the peaking. All based off these cheap castings. Taking Dr. Gas's original ideas with the air wolf heads and going farther.
