My 1969 shop manual shows for a 351W without AC, there is not a distributor vacuum control valve in the waterneck. Is that correct? I thought all cars had one.
It looks like the distributor vacuum advance in my 69 GT350 was designed to receive full manifold vacuum. Not ported/timed vacuum.

The thermostat housing has the opening for the vacuum switch but it has a plug put in it from the engine plant.
Is it an automatic or a 4spd?
Automatic. Early car #100 built in December 1968.
I think it should have vacuum port.

No ac no tree, ac gets tree, 1970s were updated

He has a 1969 GT350 without AC - I think his car has a plug in the water neck and no vacuum control valve.
Bob, it should have a square plug. No vacuum tree.
My mistake no AC no port in 1969 for his application
Thanks guys. I will have to find the correct size square plug. I have an allen head plug in there now and it bugs me.
