One guy who certainly can tackle the job of reproducing the Navarro intake is Rick Allison. His shop, A&A Transmission offers reproductions of conventional Race Hemi and Max Wedge cross-ram intake manifolds. Shown here is the A&A 440 port cross-ram. With its smaller 440-sized ports and a set of box stock Edelbrock Performer 500-cfm carburetors (PN 1404) it idles great in traffic and is totally streetable. We'd bet a Sixteen Pack could be very tractable with some tuning. If you want one, let the guys at A&A and H&H know. A small run of Sixteen Packs could be in the works if demand warrants it.
