      I understand it can simplify things in the bay, but... why?? have you given up on CIS?
      PM me when you pull it all, I'll pay s/h to take it off your hands.

      Webers are awesome and very tuneable... but I highly advise you do lots of research before you do this swap. The cost is high, the rewards can be high if you can tune them right... but tuning webers initially is a learning process, getting them synched isn't so bad once you rough tune, but getting them dialed in for winter and summer the first time around has driven a lot of folks to just give up.

      If you are giving up on CIS because it's too annoying to work on, you won't enjoy the webers anymore.

      If you are cleaning up the bay and looking for some more fuel, go for it, a set of dcoe40s or 45s would be awesome.

      Carbs are not easy. They can be a big PITA. If you don't want to deal with it CIS crap anymore, switch to digi.

      Carbs are just sex, not hard to play with and sound awesome.

      To each their own.
      CIS setups only become crap when it they encounter the unfortunate misguided, misinformed, or mishandled repair approach. Too many CIS cars suffer from tinkeritus caused by people that had no business trying to repair them.

      You can run the stock stuff with an ignition box of choice

      You don't have to remove it. But it makes it easier to remove all the wiring you don't need. IIRC the only thing you'll need is ignition, starter, fan and all your sensors (as far as wiring goes). Everything else can come out.

      I am learning as I go with this conversion. There's really no step to step guid on how to do this. On this project I'v only started removing cis parts and some wiring. Had to stop because I have one striped intake manifold bolts. so going to pull head to easily remove bolt. so waiting on gasket to come it.

      You are going to need new intake manifold bolts, 3/8 brass fitting, 3/8 hose, 5/16 fuel hose, a brass fitting for vacume advance, new intake manifold gasket, a way to grind intake manifold to fit around exhuast manifold, and you have make a custom braket for thottle cable.

      Everything CIS, emissions, and fuel related parts (your replacing with new) can be removed.

      The kit come with vauge installation instructions.

      You need the PSI reg. because your CIS system cranks out to much PSI for carb and if you keep your stock pump on you'll eventually burn it out since it's a high PSI pump.

      I got the 32/36 progressive carb kit. Came with carb mani linkage filter and gaskets and I ordered the 6psi in line pump it all came to a little over 550. It's super easy to install and comes with directions i run it with a 268 tt cam. Runs awesome
