Holley Avenger TBI install thread

[derf]

So I've got the major batch of parts in. I might as well start a thread.

It's going to take a couple of weeks before I start the install. I have to do some more prep work and wait for a couple of parts that I forgot to order (like a valley pan gasket)

But here's the first set of boxes.

I had to put something together...

Obviously, the manifold is the Edelbrock 2131. Performer non-EGR.

The FI system is the Holley 550-400 unit. It's the 4bbl unit for 200-400 HP. Should be just right for a mostly stock engine and exhaust.

Looks like a nice setup. Self-tuning and timing control sounds nice. Please keep us posted on your experience installing/using this product. I like it when people try new things. By the way, what distributor do you plan to run and do you plan to use the Holley computer for timing control?

I'm going to experiment a little.

I have a spare distributor. I'm going to see if I can lock down the mechanical advance in it. I saw a post on another board years ago about using chain links to replace the centrifugal weights and removing the vacuum pot.

If that falls through, I'll fall back on an MSD distributor I have rather than saving it for a future project.

Regardless, I have an old dead motorcraft ignition box. I'm going to gut it and stick a GM HEI controller in it, reusing some of the stock wiring to keep a stock appearance to it. Then I'll rig up the Holley computer to control the timing.

Good luck, great system, I have just installed the exact system on my CJ-7 with 400 cube SBC. I went with the GM small cap HEI because I thought that it would round off the system best.

I must admit I am very very happy with the product, it works brilliantly and I am so happy to have got rid of the quadrajet and manifold I had on my motor.

One word of advice, the only problem I had was a very bad stumble on hard acceleration from idle which I could not sort out.

Turns out that the factory setting for the powerjet fuel enrichment was way off for my application, turned it way down to setting 5 on the handheld (lowest value) and the stumble has completely gone. Looks like I was pumping too much gas on hard acceleration.

What a simple system to fit and work, congrats to Holley!
