Looks like a Edellbrock performer RPM. But it's not. It must be Chinese knock off. I was planning on. Using this on a small block mopar 340 LA. It appears to have both holes for LA and Magnum engines. Has anyone ever used one of these?
Is this a good Intake? I toughtI was purchasing an real edelbrock performer RPM. Guess thT why it was cheap. Please advise me if anyone has experience with this intake. Thanks.

I you do a Speedmaster intake search you can check to see if they are the same. It also came with both bolt pattern. I posted before and after porting numbers and lots of pictures. I sold it to a member. I was hoping it was based off the LD340 but the runners were more LD4B (318) sizing. A nice gasket match and unless it’s a strip only car you will probably be happy but it not an RPM.
 
Having run both, a lot depends on what your doing with it & the goal your after. I’d have to say it’s not a bad intake but it sure isn’t a rpm! In a general passenger car use or mild performance, it’ll be fine.

What’s the future 340’s combo of parts?
 
Sold under a lot of different names; Speedmaster, Crosswind, DeepMotor, et al...
Chinese AirGap knockoff, but as stated; not a race intake, but depending on your build it's not a bad street intake and a cheap way to get a 4bbl. on a Magnum. Not quite 340 ports, better than 318 ports, decent match to Magnums. A little cleanup work can get it working decently with any of them. Heck, it seems like even the real Eddies lately have needed work to get them ready to use.
At under two bills, compared to 400 and up for the RPM and AirGap, it's a good consideration for a budget build.

That’s true. Ores shift and if the worker on hand doesn’t know any better…. Or the foreman above him say don’t worry about it….
 
I'd still love to know if there are differences between the different ones marketed.
They could all be from the same casting foundry...or they could be different.
Hard to tell with all the fly by night MFG that goes on in China.
I'd like to know if any of the offerings are better than others.
Especially since there's such a wide range in experiences from "they suck" to "they're great".
 
@YY1 I have no issues with mine. The runners are slightly different in shape and smaller in size. It’s on a 10.5-1 - 360 with a Thumper cam @ 230@050 topped with a 600 AFB and headers.

To read one above that ram 11.60 in the 1/4 is encouraging for sure.

I've tried them from 2 different suppliers, SpeedMaster (Black Friday specials) and DeepMotor (about a buck and a half at the time, slightly more now) and they were identical. Even the same bag of hardware included.
Currently running one on my 5.9 Mag powered '88 Dakota with a stock bottom end, 600 Holley, and a warm .480 lift cam. No ETs, but she defends her honor quite admirably.
 
I have 6 of them currently. Cannot beat them for the price. I had to grind on them slightly running fabricated valve covers on small block but oh well! I also run the DART copy on my sbc. never any issues what so ever

On your WHAT!!!
 
Can’t argue that there cheap as heck.
 
Last time we tested one of those It scrubbed nearly 40 horse off one of our BPC4085CTC engines. Take that for what it's worth. We will only use the edelbrocks.

Oh, I'm sure they were not much good on your 408s- like I said, the ports are a compromise, but not a bad match for stock heads on a stock-stroke Magnum. No way I'd run them on a stroker, though. Not without a LOT of work, at least,and at that point I'd just get an AirGap or Victor.
 
I’m with you guys. I used the chink knock odd on the sons truck because it was cheap and it’s not a powerful build I’m after. Honestly the whole engine has its compromised spots. It works well enough for what it’s intended for.

I’m using a Edelbrock RPM on my 5.9 Magnum and would not change it out for the chink intake.

Right! On a 318 or mild 360, if I had one sitting there free I would probably run it.

but yet an enginemasters 318 motor, under 10.5 compression and with a flat tappet cam made 477 horsepower at the competition with one
several very sharp cookies involved in that impressive build.
find it hard to believe they ran a crosswinds intake with a 40 horse liability instead of just using an EdelBrock.
heck that little motor would have made 517 horsepower

Was it down a lot throughout the RPM range or mostly near peak power RPM?

I like that you all chose to keep the extra power on your crate engines instead of using the cheaper intake that is down power.

Interesting comparison. Was it as cast? What RPM?

Well peak for sure. I honestly don't remember how much it suffered across the board. A junk lawnmower grade air filter can scrub even more. Seen a white paper filter scrub over 50 on a 427 SBF.
