Aluminum Intakes - What are You Running?

This is my 71 Duster that 318 went in…painted steel bumpers…wasn’t what I would have done, but bought it as a roller

guy kept coming in my store, said he had one just like it in high school, made me an offer on it I couldn’t refuse….kinda like a horses head in your bed in The Godfather..lol
 
The engine masters did have a thing on cost vs HP.
If they didn’t port the intake, I’d be surprised as it has no cost involved when the own order the intake does the work vs sending it out to a professional service.

Id have any intake used for (that or other) competition ported. For the street or fist savings on bracket racing, whatever, owners call.

I didn’t see any work to it.
 
IMO, I do not think it’ll lower the rpm. I do think, IMO, that it would add the ability for more RPM. What it would do with that very specific cam… dyno time, I’d like to know. I’d say more available rpm doesn’t mean it translates into more power every time. It seems like it should, I believe it would, but the specific combo, not so much the one posted via your link, may not benefit. Sometimes, that’s all there is and sometimes there’s always more.
 
In the 1/8 mile simply swapping from a ported Weiand Action+ to an ootb Edelbrock AG (extremely dialed in combo, requiring minimal carb tweaking iirc) I went from bests of 7.78/7.80@ low to mid 87 mph to 7.65’s @ mid 88 Mph, knocked off about .05 on the 60’ times. That’s what my myriad of time slips show but as always:

“YRMV”

So far I've run Performers on a few engines, an RPM Air Gap on a Magnum-headed 360 and currently a port-matched non-Air Gap RPM on my 360. I went away from the Air Gap because I was getting carb icing issues driving on the freeway in colder winter weather, the temp of the manifold is also very inconsistent on the street which screws up the tune. Putt-putting around town it gets just as hot as the rest of the engine but get on the highway and the temp drops drastically from the constant air/fuel flowing through it and the "draft" in the engine bay.

I do want to upgrade to EFI at some point as a long-term goal is to supercharge my 360. Once I do go EFI it'll get a single-plane intake, dual-planes are pointless with EFI and don't have even air distribution to each of the runners.
