Hey, Mike- Any decisions or forward motion on your project? Let us know when you determine your path forward! I've been keeping this thread in the back of my mind, hoping something exciting might come of it. Thanks

Because this is a project motor and not a customer job, it will happen in the background. But I plan to have the WUR and Fuel Dist rebuilt and modified by a local shop who claims he can do it. Then I'll run the engine in my car and see how it pans out.

I'm just waiting for pistons before I have all the componenets and then move forward with assembly.

On another note, I just completed a client 3.5 engine with some pretty big cams. It did run with the stock CIS but wouldnt idle.
So I then fitted my Holley Sniper test setup to try.
Surprisingly, it was able to idle OK and I think this would work and cope really well.

Here's a vid.

Clever engineering Mike!

I have been thinking of contacting Holley on using one of there ECU’s to manage
an ITB injection setup.
