I’d say 90% sure that lid was not cast from that plyboard lid, holes are in the lid with 1/2” spacers used to get linkage up off the lid.

The first attempt was the plywood. Then a mold was made for cast aluminum. two different animals

Yes, I read the article too.

I actually have what I consider one of the finest examples of the Weiand P3690982 6bbl intakes available. It is completely stock other than the intake runners have already been nicely radiused to remove the sharp 90° corners where they meet the floor of the plenum.
I would do the mods 6BBL FLASH did that are pictured and explained in the Victory Library post by him.
The problems with me using that on my BMP 572 as I see them are:
I'm trying to keep my N96 hood, and it definitely won't fit.
I'd have to get someone like Wilson Manifolds to mod the runners to match the Max Wedge port size of the TF270s.
From what Rossi said, that intake is over at 6,500 RPMs, not that that would be the biggest problem.

Tests done for DC and mods


I have the Chrysler Performance book that details the specs and mods for both the Weiand and the Edelbrock 6bbl aftermarket intakes.
I've never seen the jet recommendations drawing or some of the details in the docs you posted. Thanks.

I won't know how it fits until it's in my 70 V-code Roadrunner.
I'm going with the Indy ModMan intake, CNC'd to MW port size by Indy, and my Promax modded Holley carbs, which I will rejet (I have 2 kits with 2 jets each size per kit from the #60s into the #90s). The rejet will be a best guess so the builder can run it before I pick it up or have it shipped to me. Once I have it installed, I have an Innovate Motorsports dual wideband O2 sensor system that I can fine tune with.

This 6bbl set up spun out 684hp on my 493" RB and fit under the factory Shaker. The build and dyno run are still on Hughes website. I'm switching over to the Wilson ported EFI intake on the left in the photo. My shaker hides it anyway.

Hughes spent over a week porting the intake to the limit of their abilities. Dave Hughes said its the most flow and port equalization they have gotten out of one yet. If anyone is interested in the intake and carbs, let me know.
