I would love to PM you but I'm getting a "cannot do" error when I try. Might be my iMac/Safari setup, it's also hard to get pictures sometimes .  Anyway, my email is martyk2133@gmail,com. I am eager to hear your experience.  PS Been up to the shop in Auburn and that guy is WAY past expensive, he quoted me $25-30K to do the engine. You are also correct, he does really good work. NO such thing as hijacking here. Everyone is welcome to join in.  Personal experiences shared by all is the way we learn from each other. I have a bunch, most of which you can file as "I wouldn't have done that"!!!

Marty, I just went thru a similar exercise on an Algon FI unit for my Yblock. I don't want to hijack your thread, send me a pm and I'll tell you what I learned if you're interested.

That would be fine if I had a full intake manifold. I'm working with a 368 that has a valley pan. Fitting a vacuum line in to all eight plenums poses a huge issue with fuel and throttle linkage also to be addressed.

For balancing Weber carbs, I use a Unisync tool.  Works also for individual throat fuel injection or those manifolds where the carb venturies are being aimed at specific cylinders such as when using the Man-A-Fre manifolds.

To get an accurate vacuum reading you need to have a common plenum.  With IR type induction you can't get a good reading because of the pulsing of the intake tract... The same problem comes up with IR injectors converted from mechanical to EFI.. It is solved by tapping an 1/8 pipe fitting (or smaller into each injector then running the lines to a small common plenum, then taking the vacuum readings off of that.  I will see if I can find a picture for you

Do Webbers not have vacuum ports for that purpose?

Vacuum is going to be an issue. With my custom made adaptors which fit between the runners and the heads, there's no good place to get vacuum. I know external is an option but checking vacuum for tuning has got to be in the equation somewhere.

You will likely have to do your own linkage design with bell cranks heim joints and turn buckles.. Kinsler fuel injection has all kind of weird hardware to make their injector linkages work.  You might look at their catalog.. You might also get some help from Alkydigger .com  he does custom linkage setups for Hilborns which pose similar problems as your webers. Glad you got that 368 running   Now let's make some horsepower!

We're up and running. Cam swap did the trick. All cylinders at 145. Now for the fun part(?) Fabricating the webbers with linkage, fuel delivery, and transmission linkage.  Still looking for generic linkage and fuel systems on the internet.
