I know a guy using it on a small block. Says its better in every department. Ultimate peak numbers might be similar but he says it's just stronger through the rev range, starts better, idles better, tip in better, fuel economy better.

We ran one on a mild 445 engine.  Seemed like a nice kit - more capability than the competing FAST system.

Truck oriented 445 cube 390 stroker.  As basic as they get with a twist.  Iron D2TE heads, Comp XE262 cam with 218/224 duration and .513 lift, 9.8:1 compression, Performer (not RPM...) intake.  Unusual item is a MSD Atomic EFI.  A pretty cool little unit - still tuning and hope to eventually get over 400 HP.  As of today we are now at 393 horsepower at 4800 RPM and 508 pounds at 3100 RPM.  We've been trying to get more power and keep getting more torque....  Pretty strong for a simple build.

Barry, are they gonna put it in a pickup or something bigger? I have a 56 C600 I`m thinking of putting a 390ish in. Will be a toy hauler that will look like a very big pickup.

I haven't tried the MSD, but originally didn't like the idea because it adds a booster to the venturi, adding restriction that I can't see a good reason for.  Especially with the good injectors nowadays.  I am sure it helps turning the corner into the airflow due to packaging, but most others just stand the injectors up a bit and have a more open airflow path

However, guys love how it runs.  I haven't heard one unhappy customer

One warning, it claims that it can be run without a return, true, but you need a square wave voltage controller for the pump, which adds about 500 to the cost. In most cases, I would think running a regulated return would be more effective and probably more reliable long term
