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

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

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.

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.

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.   

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.

Very cool build, modern power with rare old parts. Nice work!

FWIW - I did an AI comparison of all the pictures and it came up 100% certain it was Dove :) and all the reasons it told me so.  It even sent me for more pictures to prove it.

FE Technical Forum / Who knows their SK castings?
« on: April 22, 2026, 04:56:25 PM »
I have a customer's build here, and it has an SK cast aluminum block.  Clearly an old one. My customer bought it assembled, and it needed some help but is in very nice shape overall

The VAST majority of these are copies Dove, but this one has some more unique things, and I am trying to make sure we aren't heavily modifying something rare.

I did as much searching as I can, and three characteristics seem to indicate a real Ford SK.  1 - SK casting that is a little crookedly spaced, 2 - sleeves with steps at the top, and 3 - a stamped XE number somewhere. 

The first two are good, but the darn thing was coated in Glyptal, and externally in black paint, and I can't find any stamps yet.  I am considering having it vapor blasted on the paint surfaces, but even with that, leery to start affecting the surface negatively if it is one. 

Anyone here know SK block details?  Jack Tindle is on the road, but thought it was a very interesting block by text, Jay Cushman has the pics but I haven't heard back, anyone else play with these?

If it's a Dove, it'll likely end up a snotty little flat tappet motor, but if it's worth something, we'll likely reblock and he can get some value out of this one. 

For some reason I haven't been able to hang JPGs here lately, all the pics are on the old forum.

Thanks!

Sorry for being parochial, but I still can't support a Chinese casting regardless of it being finished at home just to save a buck.  I know it's a sign of the times, but 25.5 years in the military and seeing that emboldened theft in so many ways, they won't come through my shop, even if I lost a sale (or multiple).   

I assume that also goes for Molnar rods?

Sorry Frank, I floated right by your post. It's a solid poke.

It is extremely unfortunate, and yes, looks to be speaking out of both sides of my mouth.  Add SCAT, Eagle and K1 to that mix too, and there are many more.  I hate it, I do try to avoid it when there is a US-made substitute as in this case. Not to mention, using Molnar stuff it isn't to save money either, so yet again another difference, if we had a US made alternative, I'd jump. In fact, my most recent build for myself (452 in the Cobra) runs Crower rods.

We are all forced to use some things with manufacturing in China.  My only counter is that I draw the line at known stolen designs.  That is the absolute main reason that I would kick those heads out of the shop, same with the intakes.  It doesn't make it much better, but at least the R&D costs are paid for by the manufacturer who then profits here.  The Stevens heads and whoever is making the intakes, as well as all the  Speedmaster stuff, and all the names it changed from, stole all kinds of stuff from MSD, from Parker, from Edelbrock, you name it without legal right to it.  It'd be criminal if done in the US between two US companies. 

Keep in mind the manufacturer sent a set to me and I think to Brent too, I had my chance for input.  Not interested then and not now.  Just think if Jay's intake adapter shows up for 150 bucks?  Should we buy them? Certainly not an unlikely scenario, easy when it's a company, how about if it's a friend like Jay?.

BTW I wouldn't be mean to anyone about choices they make to pay their bills, I just wouldn't do an engine if someone asked to do that top end, and man I hope some of my best customers don't ever ask :)

However, eventually it will fix itself, cost to entry will be too high in the US due to lower volume and nobody will do the R&D on anything that isn't high volume production, cool US made parts will stop and China won't create them on their own.

Promaxx heads are pretty decent, they put quality valves in them and the machine work is nice or it least a set of SBC that we installed for a customer were,, our local machine shop was impressed with the off shore pieces and said everything checked out good (BTW they hate Speedmaster).

CNC version by Kieth Craft  https://promaxxperformance.com/product/shocker-200-ford-fe/

i never knew promaxx did fe heads. i just had a look on their website and the maxx 170 head set up for hyd' roller cam would be most suited for my 390 build. cheaper than edelbrock rpm heads and with bigger valves and smaller chambers. thanks for the tip.
so has anyone got any experience with the promaxx fe heads?
thanks, neil.

Be sure they clear your bore and valve reliefs.  Especially the exhaust side for the valves, not much room on a 390 bore, or even a 428

Steel gear, where you get it and price depends on shaft diameter.

Depends on the dyno, Superflow has some room, a Land & Sea I used once ran truck headers, and most Stuskas need a dyno header that look like a T-bucket, they have to go out and away.

I'll be straight with you, dude.

The SpeedMaster/ProComp/et al is junk.  And yes, it's cheap Chinese junk, just like the lifters you bought. 

I don't use their stuff, but have seen plenty of it fail:  heads can't pass a pressure test, seats need valve job, guides fall out, roller rocker arms spit out needle bearings, distributors fail.

It's cheap for a reason.  You play the game, roll the dice, and see if it works for you.

and another "I agree"

Had a set of their SBF heads come through here last week, sent them on their way.  Absolute crap

Their rockers are known to have body and adjuster failures, also crap

Of note, the guys who are all responding build LOTS of engines.  Take free advice for what you paid for it, but we know junk and avoid it.

FE Technical Forum / Re: Those "new" summit fe HYD roller cams.
« on: April 14, 2026, 09:06:38 AM »
I 100% agree with Brent

In the end, assuming they hit their numbers, quality is good, and the cores are available etc, IMO these are certainly a little better than most of the common off the shelf cams.  No idea why their numbers are off, but you are correct.  Could be an asymmetric lobe, differences in putting a lobe family on an FE core, or just bad documentation or a combo of all of it. 

However, with these cams for the discount, you give up lift, which likely drives some spring choice changes as well as the obvious flow loss.  You give up some seat-to-seat timing, which with a normal retainer and 3/8 valves will want some extra pressure.   What I don't like is you have to go small to get overlap low enough to have decent vacuum on a street build, it'd be nice to have some wider LSA options. 

Assuming the lobes are controllable, some spread on those bigger cams would be better for a stroker but given the lift and seat timing it'll still be a power cost over a custom.  Saving 200 bucks is 200 bucks, but it comes with a cost.

On the flip side, there seems to be some decent split, good for stock or TFS heads, although maybe a bit excessive on a couple.

I would be hard pressed when digging deep into all the other blueprinting to recommend a generic cam, but if quality and availability holds, I can see a market for these
