Hi all. 1970 Cutlass Supreme, 350, TH350 auto with AC and cruise. Like the title says, trying to eliminate TCS and understand/eliminate any unnecessary vacuum hoses/connections. Ive read some other threads but am still not 100% clear on what i need to retain. From the photo, you can see my oem setup. The only thing I did before taking the photo was remove the TCS solenoid and place that newer vacuum line that says Distributor on the T.
That used to have one of the TCS hoses. The other recommendation was to cap the port on the back upper part of the carb where one of the other TCS hoses was. Service manual does not show my vacuum tree at the front of the intake like I have. My main question is what, exactly, the vacuum connections are at the front of the intake (the tree), in top of the intake runner (can't really see that one in photo behind the fuel line) and the front of the carb. Manifold vac vs. ported, etc... Can I eliminate some of those Ts in the lines? Thanks! And yes, I'm going to be pulling the engine and doing a rebuild. Trying to clean things up. Sorry about the placement of the photos. Trying to navigate on my phone.
Did you review this thread? It might provide clues as to the re-routing of vacuum hoses for the deletion of the TVS/DVCS. NOTE: Mine is a 1971 350 CS w/ AC yours is a 1970 not identical but perhaps close enough to visualize and gain an understanding.
