put the 2600 with trip web setup in the 77 280 today, ALMOST done, need some info.

1. using mallory unilite dizzy with a red, green and brown wire _ where to, Have the flip open little box that the original dizzy connected to (2 wire).

2. is the vaccumm bottle necessary, or can I go vacumm from the firewall tube straigt to maniford vacumm?

3.have some sort of crank case vent tube comming out of block below the manifolds, right now has some type of old "oil Breather " with nothing hooked to the output tube-- were to ?

3. what do I need to do to the vent tube out of the top of the valve cover?

4.what about the return gas line, not the supply, does it need to be hooked up and if so do I just get a regulator with an over flow feature?

5. if I want to use the 77's electric fuel pum do I have to tap into the AFM harness or jump something out to make it run?

It's too freakin late, this is to long , and I appreciate those that read and Input!! Would like to finish it up tommorrow!

Thanks

1.) Don't know.

2.) Not sure on your application.

3.) Supposed to go to the PCV valve. I don't know if your Weber manifolds have a PCV fitting.

3. #2) Vent on the top of the valve cover normally goes to the air box. You can either vent it into one of your air cleaners, or get a small K&N breather filter for it.

4.) I should think you'll want to use the return line if you can.

5.) You may need to do some wiring of some sort to activate the pump, but again I'm not sure exactly what on your year car.

Last note - if you are planning to use the fuel pump from the injection, you will need to get a good fuel pressure regulator to reduce the pressure down to the amount that the Webers call for.

A 77 fuel pump is designed for a system that runs on roughly 37 psi. IMO that pump would be overkill if it were choked down to the 3 to 5 psi that carbs need. If that would even work.

Got it running!!!! still have fuel issues, using orig mech fuel pump, but didnt bypass the elect pump on the 77 (thats next). put a fuel pessure guage inline and sometimes it showed 3lbs and other times zero. Used a holley press reg which was supposed to have a bypass but it actually has 2 outlets, one of these I put to the return line. got alot of tweaking to do but holy sh*t does it sound and pull good and strong>
