Here is the article and picture link. Anyone know anything about itThe new UltraFlow EFI manifold for the 351 Cleveland. The manifold photographed is the prototype used in testing. The test engine was a 351 Cleveland fitted with open chamber heads with standard valves and a mild pocket port job. Compression ratio was set at 8:1 so standard unleaded fuel could be used. A small hydraulic cam shaft (204o @ 0.050 , 0.272 lift, 106/114 LC) was used. This combination produced 405 ftlbs of torque @ 4500 rpm and 390 hp @ 5250rpm.

I bet that is one expensive piece of equipment.  I think I personally would prefer this type of setup (BBC shown) or having an elbow mounted on the carb pad to use either a single or dual throat throttle boby. Being able to use a EEC-IV ECM and harness would be a cheaper way out. PRICE MOTORSPORTS offers adaptor plates to mount a WINDSOR intake on CLEVELAND heads so you could use a production 5.0L setup.

The injectors are at the wrong angle also.
Better off using spacers from PME and runing a 5.0 style manifold. Cost about $300.00 for the spacers, $600.00 for the intake, and computer and wiring from the bone yard. ------------------

> The injectors are at the wrong angle also.The injector angle isn't that big of a deal. Many OEM manifolds, including
the 5.0L just shoot it at the floor. The reversion pulse takes care of the
rest. Hitting the back of the valve is for cold start and idle emissions
so most of the newer manifolds aim there. > Better off using spacers from PME and runing a 5.0 style manifold. Cost

intake. Even then it's quite a bit of work and a compromise. Thomas Tornblum
in the Pantera club runs a set-up like that on a 2V headed 351C. Here's the way I'm going: http://www.bacomatic.org/irefi/irefi.html A friend in the Pantera club is casting up intakes for 4V, A3, B351, and
C302B heads on both Cleveland and Windsor blocks. Another approach that
is fairly popular in the Pantera world is a converted tunnel ram.
Cap off the top, weld injector bungs in the runners and use and oval
throttle body (can be positioned at front, side or rear). Surprisingly,
the will fit under a stock hood (no carb or air filter height to contend
with). A friend runs one based upon a Weiand tunnel ram on a twin turbo
Pantera. You can see it at: http://www.panteraplace.com/Tech%20Info/Koch%20110201%204.jpg

Daniel, i really like your set-up.
would you be interested in donating a copy of your unit for testing on my coupe ? i would like to know what it would cost for a set-up like yours. i know i cant afford it but i`m interested in it. thanks. ------------------

project so I'm getting some of my stuff at cost. > i would like to know what it would cost for a set-up like yours.
> i know i can't afford it but i`m interested in it. thanks. Turn-key systems (manifold, 4x2 IDA style throttle bodies, velocity
stacks, linkage, injectors, wiring harness, sensors, computer, fuel
pump, fuel rails, filters etc.) are around $5500 last time I checked.
Manifold with linkage, throttle bodies, throttle position sensor, fuel
rails and stacks would be in the $2500 to $3000 range. Kelly's not
sure on the manifold price yet until he hears back from the foundry. Dan Jones

Thanks Dan for the info. I always thought the injector had to be aimed at the valve.
I like the Tunnel Ram manifold idea. How did he do the top section?
