Edelbrock Air Gap Cheap Knockoff
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!
