Buick 400, 430, 455 EFI System

When you purchase your Buick 350 EFI System from Mass-Flo EFI you get:

• Four barrel TA Performance Stage I intake manifold.


• Our own custom 1000 CFM 4 bbl throttle body. It features all aluminum and stainless steel construction, sealed ball bearings on the throttle shafts, and progressive linkage. Comes complete with idle control motor and throttle position sensor. This is absolutely the finest 4 bbl throttle body on the market!


• Jumbo fuel rails and mounts. Rails have 9/16" diameter bores providing excellent flow and dampening characteristics.


• Our custom compact high flow patented mass air meter. The air meter is concealed within the air cleaner of your choice to maintain the vintage look! Systems are also available with our patented Pro-M mass air meters for draw through or blow through application.


• Complete production quality wiring harness. This stand alone high quality harness allows easy installation of our EFI system into any vehicle without connecting to your existing harness. For ease of installation each harness connector is individually labeled.


• Production mass air sequential electronic fuel injection computer.


• Eight high quality fuel injectors, sized to your application. The injectors are sized to allow ample room for large increases in horsepower. These fuel injectors are held to much closer tolerance than typical production injectors.


• All needed sensors. Most of the sensors are mounted right on the injection system for a simple install. No crank sensor to complicate the process!


• High performance billet aluminum distributor complete with ignition module, rotor and cap. Our entire ignition system is contained within the distributor and ECM. Just install the distributor and plug it in to the harness. No spark boxes needed. However, after market capacitive discharge ignition systems, boost retard systems, nitrous control systems, rev limiters and shift lights can all easily be added.


• High performance coil featuring faster rise time and increased spark duration for increased performance. This coil comes with heat sink and mounting bracket.


• Throttle body base gasket, throttle cable bracket, assorted hardware and fittings and detailed instructions for a simple turn key installation.

All of these components are absolutely the best quality available.  Unlike the competition, we will never sell you something that is "good enough" just because it costs less to produce.
