An HEI distributor will not fit- but I don't think you want one. The best solution is a Holley (MSD) "Dual Sync" distributor which does fit, as this gets you not only ignition, but crank and cam sensors as well in one package. One plug and play connector into the ECU.

Here is an early mock up on a 389 with the factory distributor shown. No room for a large body HEI. This engine has the rear mounted PCV, the kit also allows for a front mounted PCV, as well as the aftermarket (Tomahawk) valley cover. The factory valley cover also fits fine.

The green risers are 3D printed mockups for packaging and general arrangement. I must have made 15 versions of these before getting to the final version which are 5 axis machined from aluminum. Production units will be cast aluminum.

The random round dots that are visible are targets left over from the scanning. The entire block, heads, supercharger, etc were all high resolution scanned.

I am impressed to say the least. I gather the Eddy distrbutor from their Pro-Flo 4 setup would work here too? Guys with the Eddy setup may be able to step up to forced air with your setup almost seamlessly.

Another thought is another lid may be able to work with the OEM shaker setup.

I made a dozen or so of those for LS3's so there is a small market there.

Yes, any full sequential port injection ECU will work, including the Edelbrock Pro-Flo 4. The Pro-Flo 4 distributor will work as well. The injectors in the units that are currently built are hidden under the blower in the valley. They are the “shorty” Bosch 14 mm tip injectors with the EV6 connectors.

For the longer injectors that may not fit under the blower, such as with the Pro Flo 4, I have provided another location on the riser that will accommodate virtually any injector.

Here you can see in the 3D printed mock-up the injector locations for this configuration.



The injector locations are machined into the castings to order, and you can have either location drilled. Or if a guy wants 16 injectors, that’s possible too.

It’s no problem to make a billet lid in any configuration you want, including a shaker style hood, but billet parts are not cheap.
