Need some input for a 1974 Club Wagon 302 Windsor
Hi Folks,
I'm in Germany and a friend of mine asked me to check his '74 Club Wagon. It starts hard and anything past 1/3 throttle leads to engine vibrations. As a starter I checked the firing order. Now I need some input to dig deeper. A vacuum diagram would be very very helpful. What's the basic IGN timing of the 302 2V engine? What is the basic points setting ( not dwell but the contact distance) ?
Thx a lot
cheers
Harald

I took some pics with the doghouse removed. So far I couldn't get my hands on a year correct vacuum diagramm.
Basicly I have the distributor vac with two connections,
one water vac switch with 3 connections in the manifold,
one with two connections also in the manifold, close to the right head,
one vac connection at the EGR valve,
a ported vac connection at the carb and
a 3 way vac connection at the manifold where the brake booster is connected.
The vac modulator of the tranny has two connections, in the moment manifold vac on one side and the other side is open.
There are definately some glitches in these connections.
cheers

Timing is 6* BTC, but every Ford I've had likes more timing (10-14* BTC) Looks like old spark plug wires, that maybe his problem. Points setting, dwell is more important than the gap, the gap is a starting point, once you've gapped them, then you work on the dwell setting, by changing the gap till you get the dwell correct. (and once you do, the dwell changes with the wear in the points in service) The forward distributor vac port is advance, the rear is retard, both are routed to the switch at the T-Stat housing. The rest I can't tell you, other than you can get rid of all of it except for the vac that goes to the transmission modulator valve. The distributor really only needs a hose from a port above the throttle blades to the front port on the distributor (ported vacuum) All the rest of the stuff was for emissions crap.
