They're modified big block Mopar with a 10-degree adapter plate on each side.
The Mopar uses a 70-degree intake port angle versus the Packard's 90-degree and the Packard pairs of ports are about 1/2" farther apart than the Mopar. jack vines

Interesting and well done. I looked at the Mopar intakes at one time before I scored the 2x4 Caribbean.
Back in the early 1970s My H-O Racing partner and I built a 2x4 "Tunnel Ram" intake for our Pontiac high-rpm race engine. It was modified essentially the same as you described, i.e., changed the head entry angle and interdistance, but we had to "slice & dice" it because the SBC intake we started with had #1 (D-side) cylinder forward-most in the block and Pontiac has the #2 (P-side) cylinder forward-most. Doing it that way definitely works! Good luck! Craig ![]()

This intake started as a Mopar Torquer, cut into four pieces, aligned with the Packard ports, welded back together, the top milled flat, a plate welded on for the blower mount pad.

Yup, exactly what we did with the Chebby intake on the Pontiac.

The last one of the custom built Latham axial flow superchargers, with a custom-fabricated drive system. Kids, don't try this at home. The manifold, injection and supercharger system, I don't wanna know how much it cost, but there are weeks of custom work there.

That's slick! Please post more pix of the S/C setup.
What are the EMC rules regarding S/C or T/C? For that matter, do you have a link to the EMC rules for the class in which the Packard V-8 will be competing? Craig

No supercharging/turbocharging in EMC. The supercharged engine is for my personal custom Hawk.
EMC Vintage Class Rules TECHNICAL RULES (NOTE: This class WILL use a cubic inch divider in scoring to compensate for varied engine displacement. Scored test rpm range 3000-6000 rpm) ENGINE Normally Aspirated OEM domestic production passenger car V8 engine types or families introduced in 1954 or earlier. Any Hemi from Chrysler Corp prohibited. Other antique engine families introduced after 1954 allowed by specific listing. Listed engines include: Nailhead Buick, Y-block Ford, and Chrysler 1956-1967 A-Series Polyspheric small block. Power adders prohibited. Any method of artificially heating and/or cooling engine fluids, fuel, and/or air prohibited (not to include thermal or friction coatings). This includes, but is not limited to, heating and/or cooling by mechanical device such as an external cooler or radiator/heat exchanger, pre-heating or cooling of any fluids with an oil heater or fuel heater/cooler, or the addition of a temperature-altering device designed to cool or heat the incoming air charge by mechanical means such as an intercooler, chemical means such as a chemical to cool either the incoming air/fuel charge or intake manifold, or electrical means such as an electric oil heater inside or outside the engine. Aftermarket SFI spec 18.1 harmonic balancer mandatory. DISPLACEMENT Unlimited displacement. Cubic inch is calculated by bore x bore x stroke x 6.2832. Bore is measured at top of cylinder where ring wear is not evident. Bore and stroke are measured to the third decimal place, i.e. 0.001. Cubic inches are calculated to one (1) decimal place i.e. 350.0. Any part of a cubic inch is rounded up to the next highest inch (i.e. 301.2 = 302) for the purpose of claimed cubic inch of engine as used in scoring. The cubic inch used in scoring will be a whole number; no decimal part will be used. ENGINE BLOCK Any domestic OEM passenger car or commercially available aftermarket OEM replacement, cast iron block of a legal engine family or type permitted. Engine block must retain OEM cylinder bore spacing and OEM block angle. Lifter bores may be bushed. The responsibility for adapting to the SUPERFLOW/DTS dyno cart is that of the participant. MOTOR PLATES Front motor plates allowed to facilitate engine mounting CRANKSHAFT Any commercially available crankshaft permitted. CYLINDER HEADS OEM or commercially available aftermarket cast cylinder heads manufactured for the engine type permitted. Heads must be originally manufactured for the engine application in which it is being used. Billet heads prohibited. Any valve seat size and/or valve size permitted.
