It was a "opinion" that the SM heads are higher quality than Edelbrocks.
Not a direct comparison. Builds were different and the SM heads made a tad more power. Proves nothing.
We all have opinions. SM heads have slightly bigger ports stock. I can see it.
But until someone makes 740 on pump gas, stock block. Near 800 race gas or 900+ on a 535 SM heads are not better than Edelbrocks.
Yep, opinion.
We will probably never see a wide port SM head. Someone will have to go through a LOT of trouble when they can just order E heads with no pushrod holes.

No it was not. He look at both of them. Also please learn the difference between quality and performance. I has seen some heads that needed stop leak in the engine so that they wouldn't leak water into the engine set a nation record.

Mike's was bigger. But again it DOESN'T matter both heads can physical fit the same valves!
Just because most haven't doesn't mean nothing or because 1 didn't it with HP heads doesn't mean it should be done either. Just means it can physical be done.

No, The SM heads made less power 1.6 less and 36 less torq, But with less
flow 5cfm less compression 3/4 of a point and had the stock valves.
I almost matched the power of the E-Head motor with the SM motor.
Other then those differances I was pretty well impressed. I can only
Emagine what will happen with more head work on the SM heads.
It's only a matter of Time.

Other threads have corrected the made in China line. Yet it continues to prevail.

I bought a SPEEDMASTER !! 5 gallon fuel cell the same time some you bought heads in their last sale. Right on the box it says "Los Angeles, Sydney, SHANGHAI !!"
So, lots of people in Los Angeles are into hot rodding. It used to be the mecca of it. Plenty of Australians race American iron.
Hmm, Do folks in Communist CHINA, as in Shanghai race American iron ?
Well, I would say that is a big fat no. Those people have little FREEDOM to be into Hot Rods or race.
But what we all know is they "produce" lots and lots of parts for American Hot Rods. And they care little about copyright or manufacturing laws. I also bought a T400 yoke I am having second thoughts about actually using. The bar code on the box is fuzzy. Neither box,s say country of origin. Which is required by law. But we all know they care little about laws.
But Australia does, they would say its made in their country with pride.
I would say manufacturing is Shanghai,s end of the deal. Otherwise why would it be on the box ?
Until proven otherwise Made in China is my educated guess.

Which is less patriotic, buying speedmaster heads or buying speedmaster fuel cells?

Putting a Speedmaster cylinder head on your car. If it were not for the Edelbrock cylinder head the Pontiac world is a barren wasteland. They deserve the credit, and profit.

Looks like someone it throwing stone in their glass house.

Edelbrock designed their heads off of a Pontiac round port...But Speedmaster is a criminal for designing a similar head?????

Seems like you are putting a lot of energy into this.

And, lets not forget that Edelbrock WAS NOT the first aluminum aftermarket Pontiac head.

Racers forget about Wensler…..if it wasn’t for Wensler there would be no edelbrock, hell KRE would have better the e head out……they did with the aluminum d port! Just saying!!

Compare Edelbrock head prices for Pontiac compared to other makes. I have no problem saying they are screwing Pontiac people. I enjoy seeing the competition.

You guys crack me up buying chinese products.

I'd like everyone to get up and check that label on any piece of clothing, or the computer or phone you are using or the shoes you are wearing.

Another thread gone down the crapper.

The OP has a running engine and gave his results.
I have 3 sets of E heads and 2 sets of SM heads. I also do my own work, the SM heads are a decent head for a street/strip car.
You keep talking about these engines you are gonna build etc and keep throwing peoples names out there like you break bread with them daily.
How about instead of slamming everyone's build you spend the energy putting yours together and show us your Real World Experiences.

In fact, I will haul my home built, stock suspension, stock block, factory crank, Carter AFB fed 3750LB full interior street car all the way to Vegas for a match race with your light weight gutted 69 race car for $$$.

Mike, have run any of the SM heads yet? Or are you still running the E heads?
