$trainman Posted April 13, 2011 Share Posted April 13, 2011 I know you'll must be getting tired of all my questions, but, the beast is almost done so please be patient. 72 350 4bbl 350th trans. there is a what I think is called a tcs solenoid on the manifold on the right side. It has 1, 2 wire plug and and 2 vac fittings one goes to the dist vac the other goes to the carb. There is 1 vac fitting on the other side where the wires plug in, WHERE DOES THAT GO!!!!!!!!!!!!!!!! I am at wits end. Thanks Again DAN Quote Link to comment Share on other sites More sharing options...
amsterdam84 Posted April 13, 2011 Share Posted April 13, 2011 Possible to take a pic of it? Quote Link to comment Share on other sites More sharing options...
Canuck Posted April 13, 2011 Share Posted April 13, 2011 This possibly goes in the back of the carb. I can't recall for sure. Most of us have removed it. Quote Link to comment Share on other sites More sharing options...

$trainman Posted April 13, 2011 Author Share Posted April 13, 2011 this part is not attached to the carb. it does not have a plunger. solenoid is probally the wrong word it is a valve. Quote Link to comment Share on other sites More sharing options...
stangeba Posted April 13, 2011 Share Posted April 13, 2011 I know 71 was a one piece then 72 changed and I don't know for sure but could the extra vacuum port be a spot for a filter like shown in the 71 drawing above? I have one of these units that I think came off my Dad's 72 350 2BBL and there is only two fittings, not three. Could yours be from a California system?

Jim Boczar Posted April 15, 2011 Share Posted April 15, 2011 On a 1970 TCS solenoid - the port where the wires attach is for carb vacuum source, on the other side of the solenoid - the port angled upwards goes to the distributor and the other port is for vacuum let off, which on a 1970 attaches to the top rear of the carb port.HTH.
