Let me point something out that many that don't remember world history, may not understand.

Do any of you remember the "Opium Wars" of the 1800's? Basically, the British tried to addict the Chinese, using Opium, from India, to control their trade with them and that is what the Chinese are doing to us today. Not only with drugs, like fentanyl, that destroy people and family's but, with cheap goods, that destroy our work force and our ability to make anything here.

Our big corporations and many small businesses, are just like those Opium addicted Chinese workers and businessmen but, their (our) Opium is profits. Kinda like the old saying "What comes around, goes around". We need to get out heads out of our a$$ and anyone that can buy American should and must, do so.

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.

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.

Excellent!! Thank you.

Jay, I'm not suggesting this for you to continue in business because I doubt that there is anywhere in the US to even get castings but, I'm curious if you ever investigated magnesium castings and their availability. I can only assume that you'd have to go to Canada to get castings.

Other than there long term corrosion issue with water and possible fire issue with chips (I used to machine it), I think it's the ideal material for the big FE intake, I know that there are mag intakes that have been done, in the past, for FE and others but, nothing I've ever seen in the after market, other than Sprint Cars. 

This is horrible news and very sad! I always have loved your innovation.

How much does the shaping of the short turn increase flow?

Geoff, I've owned 3 different K code engines. A '64 Fairlane, 65 1/2 Mustang and a 3rd that I got at work with 2 AFB's and headers that I put in the Mustang. I didn't port any of them.

My question is what might be the port difference between the small valve (1.67 '63-'64) head and 1.78 '65 and later heads? I know the 1.78 heads basically flow ~165 but, what did the 1.67 head flow?

Ford claimed 271 hp, even with the small valve but, I think that rating with be really hard to get with the small valve.

I did port a C6 head, a few years ago and got 196 cfm out of it, using a 1.90 valve, w/o touching the short turn or any of the port, back of the bowl, mostly widening the bowl and working on the valve guild boss. It quit flowing above .500 lift, too. A lot of work for someone that isn't a porter!
