Edelbrock Pro Flo 4 EFI
...
There was a big height difference on the manifolds though, so the new kit required a hood scoop to fit the charger. Also something to note, I blew up 3 or 4 of the external fuel pumps that are an option when you buy the kit. Do yourself a favor and spend the money on an in-tank fuel pump setup and you will be saving money in the long run.
For those looking to make the jump to Multi-Point EFI, this kit is a great option. However, any aluminum manifold can be modified to use with this system if hood clearance is an issue. Wilson Manifolds can install the injector plugs, port your manifold and add upgraded fuel rail mounting brackets.
Instead of just buying this kit, you can easily put you own even higher performance kit together using either the Edelbrock or Holley computer and wiring harness, a dual sync distributor from either manufacturer, a throttle body from either manufacturer or a very high flow throttle body from Wilson, some injectors and there you go. There are only so many components to these kits to make the system work.
The availability of distributors that provide both cam position and crank position sensors is a huge help for retrofitting EFI on older motors. Self-learning, easy to program software and computers and EFI pressure level fuel systems were the largest hurdles to overcome when trying to modernize our old Mopars. These hurdles have been reduced to mere speed bumps with this new technology.
Better components and an intake that fits cost a bit more, but not that much more. This kit is limited to only 600 HP, but that is mainly due to the intake they use in the kit. The computers can support much more.
As far as fuel systems go, using either an in-tank or external mounted pusher pump with a surge tank set-up will out perform any in-tank system unless you build a custom road race tank with multiple snowmobile pick-ups. I'm not talking about just the volume of flow out of the tank, but how air free the fuel is when the fuel level is low and high G-forces are at work in the tank from driving.
From all I've heard from every tuner that works with this stuff daily, the Holley computers are the way to go as far as self-learning, ease of programming and performance, but for those that want an easy to install, plug and play Multi-Point EFI system; this is a great price with promising performance potential.
