Which X ram, aluminum, magnesium, or the Mopar ???

I like the vintage look also
Are you talking about the Mopar Performance intake being worth 20 more HP or like a Barton intake ? Have a pic of yours ?
From what I have read and I didn’t get into it much the removable tops allow for internal flow mods and they overall flow better due to the casting process, ultimately being worth 20 hp. But having a 1965 magnesium cross ram is way cool imo.

As you can see the top is cast and not removable there is a part number and two freeze plugs around the base of the carbs that indicate this is a mag 65 manifold. You can also get a repro from Mancini I think it’s made by A&A Transmissions.

Comparing the pics looks to me like the bolt on tops also sit higher so maybe just the design difference accounts for the hp increase. Right now having enough HP isn’t a big concern for me.

My intake weighs 25 lbs without the carbs according to A&A so you are saving some weight over the front wheels. Also the 65 -64 Aluminum and Magnesium intakes were both used on the 68 Hemi Darts and Barracudas. So from a clone perspective either is correct....

FYI I just got the car so nothing you see is indicative of my work except the addition of the race venturis.A3A4A791-2BC7-4F2A-B92D-8CFA25D8610F.jpeg
