Edelbrock Air Gap Cheap Knockoff

I had a few that were fine. One was machined wrong.Bolt hole to head was off.Same manifold would not seal and had vacuum leaks. Chucked that one. As you say you get what you pay for. Like to gamble ?

Lots of folks have them, most report they are fine but a bit different then a true Eddie Air gap.
After seeing some posts on what you get from Edelbrock, you might just get the same quality.

Yes, I have 2, one on a 10.5-1 360 w/Edelbrock heads, 600 cfm Edelbrock carb, headers into a 2-1/2 exhaust and a 230@050 thumper cam.
The intake sat on top and the ports aligned fine. They’re smaller than the head ports. Performance is fine. Drivability is good. I firmly believe the RPM will make more power.
The second one is on a stock 5.9 Magnum long block w/headers @ 1-5/8, 2-1/2 exhaust, 750 carb & a Crane 236/.497-108 cam. It’s not yet finished but will report about it at a later date.
I also have a RPM on a stock 5.9 Magnum long block. Same as above but it still runs the stock camshaft and the headers are 1-3/4.
The runners on the chink knock off are more narrow and not as nice as the RPM’s. I think this is why I feel it has a power band from basically idle and up. The RPM on the stock 5.9 long block is ever so slightly softer from idle to 1500.
Depending on what you’re doing and expecting, the knock off is just fine for a daily driver and a stock to mild (subjective) engine.
If your more interested in making a nice street bruiser or a heavy street hitter, the RPM is for you. The RPM is what I’d spring for again. The price difference is a lot, I know. I think it’s worth it.
The Edelbrock fit and bolted up very well and the port alignment was really good, no modifications required. Check your fit on what ever intake you decide on.
There is a member here with an engine masters contestant running that chink knock off and swears it’s great but has not swapped to a RPM to see how it does. IMO, just because it made great power doesn’t mean it’s the best intake for the job.
Choose accordingly, choose wisely!

A noted engine builder, that specializes in Mopar engines stated
That the knock off edel's should are 25 hp less than a true Edelbrock

LMAO!
It was Brian at IMM engines, IIRC
If you get what you pay for then that would all Edelbrock stuff is good. It's not.
I have known Brian for 30 years and read everything I can find
that he has published!
that he has published!
That's great. The reference I made was a post here in FABO
OK…. And?????
His tests were on the Dyno, even if the Dyno is a little happy, that's a significant amount of hp. Enough to feel it in the seat of your pants
I ported a Speedmaster intake and did a post on it around two years ago. It looked exactly like this intake. I included the flow numbers in that post and if I remember right my Ugly Torquer intake flowed more than it after working both. If they had copied the LD340 and used the bigger runner size they would have made a good intake. The 318 sized runners hold these intakes back bad.
I’m not just quite sure why you quoted me and then write what you wrote. As if I don’t believe what you wrote perhaps. Are you trying to convince me of something? I’m not sure where we are at here.
The one thing I don’t know is the combination of parts. So to say, it was down 25hp is a blind blanket and misleading statement without knowing the combination.
25hp might be a lot of power when going up from 245hp but you’ll never notice it on a 600hp engine. Feeling it in the seat of the pants is a wide and varied as well a relative term and statement.
I thought it was the dude from Blueprint ( Johnny Mac ?).
You are correct!

The engine masters 477 horse stock stroke 318 I had utilized a knockoff airgap( professional products)it made great power, obviously, and performed well at the track as well.
To think it would have made over 500 just swapping to an an Edelbrock air gap …… the engine masters super sharp guys I guess left tons of power on the table just by not using the Eddie ( and this was a few years back when either was readily available and cheap)

Yup! Twas me. Usually someone jumps right in to tell me that I'm wrong, they have seen the off brand intakes do fine, so I haven't chimed in, in these off brand vs edelbrock intake threads for a bit, but I remain firm that I have personally seen the common off brand "dual intake bolt pattern intakes" take a 480 HP 408. And choke it down to 450 ish.
Threw the edelbrock back on, and boom. 480 again.
Now, that's ONE engine combo. MY belief is the smaller the cam, smaller the engine, the less it will care. Thats my BPC4085CTC at 6000 RPM. A mild 360 with a 5000 rpm redline wont care as much.
Think of anything airflow related....a 950 carb on a stock 360 will run rich, but be drivable, and still make whatever "peak" HP was.
Throw a 600 cfm carb on my 600 HP smallblock...it'll scrub 100 HP and 1000 rpm.
Think of changes by parts as percentage losses or gains.
5% gain /loss on a 300 hp engine is 15 hp. That's PEAK. what is it st 2800 RPM? 8?
5% of 480 is 24hp again peak... all wound out.
Peak is what "everyone" cares about. What you Feel is torque. And where the engine lives 70% of the time is sub 4000 rpm.
it's all relative to the engine, rpm, and what you are doing with it.
Only the user can make the call if the savings matters enough to them to chase the "real" intake vs the knockoff.
Chasing numbers? Go edelbrock.
Building a 5000 rpm truck engine with a small cam....save $***, or chase 20 peak hp. End users call.
Hope that helps the thought process.!!

Do you think the quality started to go down after Vic died?

yep, I will jump in…if you think these very obviously smart, veteran engine master competitors left 30 horse on the table for at the time maybe 150 bucks…..not sure what to tell you

I think it was somewhat before. Like maybe when he stopped being so prolific in the business. As much as I hate to say it, I don't think his business ethics rubbed off on his children. I think they simply saw a cash cow and sold out.
Couldn’t have said it better and your a seen it happen first hand guy. How can anybody argue? IDK?!
I think you put to much faith in these guys and what they used.
I know a pair of sisters that KILLED their dads biz after he passed on. They’re all about the money and nothing else. Screwing people faster than a drill gun can.
I only repeated what I read here in the past, not claiming that figure myself
That's exactly who I was referring to.
