BTW, besides Crower still making rods, Carillo and Oliver still make rods. What company hasn't copied the H beam Carrilo rods?

If you want to keep American rod manufactures in business , those are the rods that should be in quality builds.

So Brent, Before you speak for me, I would suggest that you reference the actual the thread you speak of or, give a direct quote from it! That is NOT what I said, at all. As a matter of FACT, I did not say anything about how great ANYTHING was!

Prove me wrong or apologize.

https://www.speed-talk.com/forum/viewtopic.php?t=68807

"BBM or Bear Block Motors is the best source for CI FE blocks.

You can call for availability at 818 349 0999

The FE is basically limited to 4.38 x 4.38 or 528 ci but, they are lighter and more compact.

Heads can run up to ~400 cfm and there is a new aluminum Tunnel Port head available at this time, un-ported they flow 354 cfm @ .700" "



There ya go, Frank.  Where I'm from, calling a company the best source for something is giving your stamp of approval on it.  Great....best....pretty much synonyms if I read my thesaurus correctly. 

We can go further:  the definition of "best" is:  the superlative of good or well, defining something as superior in quality, highest in performance, or most desirable and appropriate. It means surpassing all others, offering the maximum advantage, or representing the highest effort. Common synonyms include optimal, top-tier, finest, premier, and superior.

You completely skipped by Robert Pond Motorsports, who also makes cast iron blocks, and casts them in the US.    Again, you are very critical when someone mentions Molnar rods, but are very quick to recommend a supplier based out of South Korea, while glancing over obvious choices in the United States.  The clincher is that you don't have experience with any of them.  You are giving blind recommendations just based off of stuff you have read on the internet, which adds a little more fuel to the fire.

Just let me know which side of your mouth you'll be retorting with. 

Have a good one.

If you want to keep American rod manufactures in business, those are the rods that should be in quality builds.   

I think you are crossing streams. 

1 - No two rods I have seen are alike, other than close similarity to K1 and Molnar, who were business associates.  Even then, the bolt design is a bit different.  I am not buying into your claim of everyone copying.  If we want to speculate I bet we could find some old Duesenberg or some other 30's car that had an H-beam capscrew long ago.  That being said, yes, I sure would like to use all-American stuff, but we have to be realistic in what we stand for and against.

2 - As an engine builder, I cannot justify spending more than what the engine needs, I give them the option and explain off shore sourcing, but to add 400+ for rods above a Molnar (or more than that as an upgrade from SCAT I-beams) is usually a show stopper.  I would prefer to use a fully USA-made rod, but I have to accept an engine is an expense, not an investment, in fact, I have to often remind customers that, so in turn they trust and expect us to tell them when something is sub-par or overkill.  In this case, the middle is Molnar, K1, and Callies offshore (although I shy away from Callies because they are heavy).  Lesser like SCAT H-beam is very capable but heavy, I try to avoid those unless the customer has them.  Eagle....well, when you have a set machined right, they are OK but heavy too, but when you have to resize a few you get turned off quickly and cost goes up. 

3 - However, despite that, I can refuse to use parts.  Don't bring a Procomp or Speedmaster part in.  That decision can cost me if the customer leaves, and that's OK, I will be respectful and understand the position but I won't use Speedmaster stuff, both based on business practices and failures.  I also won't use highjacked stuff.  If it seems like I pick and choose, I do.  American company tasks Chinese company to build something because it's cheaper...I don't like it, but I get it.  Chinese company copies something and keeps trying until an Amercian company accepts it and badges it...different.

My opinion is this.  If you want to sit and snipe at my comments, continue, I'll keep playing

However, if you want to do a Speedmaster build and go all the way up to the Promaxx heads, 200 dollar and Speedmaster rockers, go for it.  Let us know how it runs and lasts and how much labor you had to add to the build

Additionally, you could build an all American engine with no offshore sourcing.  I'll applaud you, but it'll be a lot of money and that's a very hard decision to make on an average Joe's budget.

     B.T.W.  As far as for the manufacturing of connecting rods, Crower, on this front has succumbed to the import onslaught and no longer produces such.    :(

     Crower "Billet-Steel" connecting rods, the best you can, . . . . . .well, "could" get!   ;)

on other forums will be quick to talk about how great certain South Korean products are.

I never said anything about how "great" they were, just that, at the time, they were the best source available! PLUS, they are not made in China!!! Like the products that you and Ross put in engines.

I have never promoted anything made in China!

Ross, you will tell people to hit the road because they want to use the Pro Maxx head that cost $1000 less than the TFS and say you "have" to use the Molnar rod because it cost $400 more than a American one?

I don't think many people realize the Molnar rod is made in China, in part, at least, because both of you use them and promote them but, say you won't use Chinese stuff.

Hey everybody, I use Molnar rods.  They are forgings from China, machined in the US.  They're a better quality than most other rods out there and you pay extra for the quality.  I also use Scat cranks, because I don't believe in asking someone to pay $5000 for a custom billet crankshaft from Bryant/Winberg to build a 445/482 or spending thousands to have a factory crank customized and end up with a re-machined 60 year-old crankshaft.

In addition to all of that, yes, I realize they're made in China, but there are quality products coming from China and non-quality products coming from China. 

The quality parts coming from China include AFR cylinder heads, Molnar rods, Scat cranks, Callies Compstar rods, etc., etc. 

The non-quality parts coming from China include SpeedMaster/Procomp, etc., etc. 

As Frank brow-beats everyone from his computer/phone that was made in China about using Chinese products, I'll just skirt around all of that and tell you all that I can set you up with a full rotating assembly using Scat cranks, Scat rods, Molnar rods, etc., and it will be pretty affordable for someone who wants to build a new 445/482/496/510, etc. 

Have a good day!

China or Taiwan?  There used to be a difference between the two.  I spent time on Taiwan helping the Taiwanese people refurbish the F4-C/D/E aircraft with battle damage.  Good people to work with and good work ethics.  You could leave your tool bag on an aircraft wing at end of shift and everything would be there the next day exactly as you left it.  No where else in the world is that possible.  JMO, but to me there is a great difference when you say Chinese made and made in Taiwan.  Joe-JDC

I don't think many people realize the Molnar rod is made in China, in part, at least, because both of you use them and promote them but, say you won't use Chinese stuff.

First, I don't tell anyone to hit the road, I discuss options and if we are not on the same page, we both agree.  It's NEVER angry as you would like to make it sound.  I have seen guys come in with boxes of old pistons, heads that have been butchered, all you can do is advise, then we decide who is willing to carry the risk.  If I won't put my name on it, I don't do it.

If someone came in and wanted to use Promaxx, I would explain why I do not use any of the Stevens castings. TFS isn't the only game in town. If they insisted, I would offer Edelbrocks, repair/improvement of stock, or recommend some other guys who may be willing.  Very regularly, and similar, people come in excited about Speedmaster rockers, I won't use them either, but all I have to do is push them to Google.

As far as the Molnar rods, the range of rods, using a 6.70 BBC journal.   In order for a street stroker, I like SCAT I-beam, Molnar/K1, then expensive, for lack of a better term.  Most of the time you can get away with a SCAT I-beam for the builds I usually do.  However, if I am doing a steel crank, big dollar build, the strength and weight of the Molnar is an advantage over the I-beam, so we discuss.  The 400-dollar number is if we considered wanted to go a step higher than Molnar for US made, not the other way around.  Unfortunately, that next step is significantly more money than Molnar and then it goes back to the US-made vs US-machined discussion.

You don't live in this world, I am sure it's similar in tool making, but we aren't ladies of the evening that get paid for whatever pleasure someone asks for.  There are times a dingle ball hone and re-ring may be the right answer for the customer's budget, but I'm not doing it, just advising the risk and if needed, send them to someone who will.

Let me put one more thing out there, especially regarding rods:

If you don't buy the American product, there is no incentive for American company's to make make one and if you don't request additional products, there will never be any options made, to any base product that might still be made in the good old USA.

Think about it.

Frank, no doubt.  Are you going to run only USA made and sourced parts for the ones you are working on?  A lot of aluminum from the middle east, TRW stuff in India and South America, bearings from all over the place. 

In theory, I agree, but I (and sounds like Brent too) draw the line at hijacked patents because it's nearly impossible to avoid China completely.  I don't like that part either, but there is a breaking point, and that's mine

I don't know why these conversations usually only pertain to engine parts.  Well, I kinda know, given the instigator in this thread.

Guys will throw ten shades of gray at an engine builder for using a rod that was forged offshore, but don't take the time to research if there are 100% USA made smart phones, PC's, etc.  Even current vehicles being made by Ford, Chevrolet, Dodge/Chrysler/RAM, etc., are not 100% USA stuff. 

BTW Frank, I think you're overplaying this a little too much, just to take a dig at me or Ross.  On that Speedtalk thread, you could have easily mentioned Robert Pond Motorsports.  And it may have very well been that they were out of stock on cast iron blocks at the time, but did you even take a second to list their name or mention them?  Nope.  It must not be that important to you.

What brand of cell phone do you use?  There's a cell phone, called the Liberty phone, with 100% US made components and assembly.  It's $1999.  I assume you'll be running out and buying one after you know about this now?

Agree with Ross, unfortunately nearly impossible to avoid China altogether but i defiantly wont knowingly purchase something they ripped off from someone else.

I'll add something to this. I just received a Starrett 98-6 machinist level, and they are not cheap at $182. Made in China now.

I'm not advocating China parts, but you have to be pragmatic about it.  If we closed off all Chinese production, there would be no Walmart and no Amazon.  A manufacturer who steals designs should not be rewarded just because they can undercut the original R&D manufacturer's price.
