Speedmaster blocks....whats the skinny on these?

[houser45]

Until they are proven to have accuracy in the dimensions of core shift and material at least close to an oem block. They are a waste of valuable time and money.

As a consumer- I think of resale down the road. Will you make the money back on a more recognized block?

https://www.nytimes.com/1992/11/04/busi ... steel.html This why you have been seeing a lot parts being manufactured in China.

What does an article from 1992 that's about something that started in the 80s have to do with China making more steel now?

I was looking at getting a 351W aluminum Speedmaster block.
There was a thread on YB about this block and there was one guy who’d aquired one and commented on the quality after inspectino & measuring. He said «it was all over the place» and returned the block. (And got a Dart piece instead). That’s the one real- life example I’ve seen on these blocks.
However... Summit sell that block. To be honest I’d guess it’s not that bad... Still tempted to try one...

I just got my latest 4th china / speedmaster/procomp 351w short block built by PPP/FPS/AVG last week ... ALL IN SPEC ... very happy with it

I have learned from internet forums is you have to pick the right people/shops that are able and willing to take care of any issues that may come up,

I have learned that not many of the guys selling blocks out of there barns/sheds on forums are able/willing or have the knowledge to do that,

I have learned these type of knowledgeable guys/shops are usually too busy with work to be living/posting day after day on internet forums.

Dude, it's you alone claiming this dart cracking bs still. Same thing you've been saying for years and yet you're still the only one saying it. You're the only one pushing China crap over Dart.

Just shut the [DELETE THIS POST] up already. You haven't convinced anyone in the last 10 years that China crap is better than, Dart. Don't waste the next 10, too. We don't care that you believe that crap. You're not changing anyone's mind.

I'd completely trust the guy in that video no more than some random forum post. In fact that's why I always say, I'm not an expert in my own videos.
They are meant as a guide so any person can use my info to make their own judgement, same as anything I read on a forum or in a book. Did he show the exact split Dart blocks?

I have two brand new intakes from Dart(also had a few sets of heads) and one direct from Speedmaster. I'd buy from Dart again. I'll finish the Speedmaster intake video someday and if I find any new probelms in the future from Dart I'd call them on it but nada so far. I've even had good parts from Speedmaster but small stuff that's hard to screw up, well I got some girdles nuts for a cheap project and I gotta run a tap thru a few of them.

Kazoom, you've got to admit you have a weird obsession about Dart blocks.I've seen your posts for many years, on several forums. That is one reason why I think you are connected to Speedmaster or Pro-Comp in some way, not just a fan-boy. Or you are Chinese and have a lot of Communist pride. No way are you just solely an end user of the product.

Oh and you are also a troll. You obviously like stirring up shit.

Ouch, that's going to leave a skid mark.

[FC-Pilot]

I know I should not do this, but I just could not stop my fingers.

So Kazoom, how did its hardness test out? You said that the engine shop had to correct some stuff, what all needed to be corrected? Also, how much did all the corrections cost you? You say you have used them for a while, how many laps or passes do you have on any of them. I think it is great you are excited about your parts, but we here at speedtalk are concerned with details, cheerleading does not impress me. I would appreciate any valid details you have to share about the products.

The intent of the thread was to discuss what was good or bad about them by stating facts or experience. I have none with their blocks, but have had some with other components. I won’t go into those details as that is not what this thread is about, and I also won’t bring up details and experience of other parts or manufacturers that are not procomp, again because that is not in the scope of the thread.

kaboom you are nothing but a lying multiple screen name many times banned troll . I guess I missed your grand finale of bs to get your screen name for that day banned from yb . I wish I would of quoted all of your nonsense that I replied too , not sure why it got removed .

[canuc]

kaboom look I know you'd like me to be upset but like I said on yb I'm just happy to be done with crapmaster . It's obvious you'll use any means to get a chance to spam crapmaster , you didn't ask if the block had a 1750 special price tag you said 1250 , but like I already said your a liar . And to answer how the crate was labeled it just said 351 engine block , nothing about it being a clearance or blem or anything like your trying to imply . At least one thing your owning up to here is being a mutilple screen name troll .

[Chris_Hamilton]

How about some video of those running engines Kazoom? And because I'm a doubting Thomas, I'd need to see your screen name in the video, like on a piece of paper. If you have four built running engines it shouldn't be hard to produce some video.

Just saw some pictures of some new SBC Procomp heads, looks like they did everything to add metal to hurt air flow rather then help.

[canuc]

here you go kaboom a finished block nothing else noted .

[lefty o]

MAN, I can rrreally feel the LOVE in this thread

Hi canuc, i heard these blocks should come with a "spec tag" showing spec's & i think something about who in usa machined them?, if that pos $1550 block is as bad as you say, clearly its not a blem & should of been melted down like some of the other american dart crap. Anyway I am glad you are done with that $1450 pos block & have moved on with your life. So im speculating the problem with the legendary sm/pc Quality Control is the american language barrier, not sure but i think not being able to speak mexican (californias official language) could be the problem here

& hey, you know what they say about trolls... takes one to know one , as i said before, i have about the same amount of user names on YB
(about 1250 or so) as some of the loosers living there lives on the YB forum

so funny you expect me to supply you with vid clips & passport now , especially that I just got the forth one just over a week ago,
but hey no problem, send me your vidcamera with instrutions how to use it and i will get right on it just for you.

man!, its so nice to meet another expert like yourself on sm/pc heads as i DO have a few sets of them ...
here are my latest ones i just got... https://www.corral.net/threads/351c-ave ... t-18666277

with some close up pics of ports... https://www.corral.net/threads/351-clev ... st-9822418

you got some issues buddy.

[Chris_Hamilton]

Kazoom, you said you have four of these. You also mentioned you had one running in a mudbog(?) truck. Shouldn't be too hard to take some video with your cellphone of one running. Being that you are such a big supporter of them I would think you would want to do so. Short video, with proof that it's you, close up of the block and upload it to youtube. How hard is that?

I don't expect that you will as I think you are a Speedmaster Shill . But prove me wrong, post some video.

Way I see it time to put up or shut up.
