Hey guys, hope all is doing well.

Quick question.  I have a 56' 272 and I am putting on a 3x2 setup that I just got.  I am running a Turbo 350 trans and a post 57' distributor setup with the ignitor 2.  I am adding a picture so I hope it comes out ok.  I am assuming I would run the temp sensor for my fan relay in where the black circle is, and a tee off of the hole with the red circle to both my distributor and th350 vacuum.  

Does that even seem right?  Sorry for the crazy questions, I am no engine guru, but I know a lot of you are.

Thanks in advance!

  

The black hole is normally for the heater line but I guess you can use it for other things. There are adjustable probes that slide in between the radiator fins that are popular now and many like.

Thanks Dry Lakes.
I am using the Wilcap adapter.  I had the TH350, so I just went with that. 


I am building a rat style truck, so no heater, no a/c (other than the windows, haha).

I have the same rig 3x2 and TH350-minus the dizzy-I have a Mallory with mechanical advance.

There was a boss in the back of my manifold that I drilled an tapped for the TH350 vac (yeah I had a freebie too) -used a Bendetsen adaptor.
The TH 350 can also be built to not need a kick down.-both help clean up the manifold area

There are a few that have base spacers for the 94s and 97s that have vacuum ports-I may go that route. My 94s are really prone to boiling and some amount of spacer may be handy also.

Sorry guess I should mention the vendors-they have them at Dashmans (I use they're phenolic spacers) or Vintage Speed.

I  won't comment on the vacuum hookup situation. However.. unless you are converting the engines up from a 2 Bbl setup, don't expect huge performance gains from those Offenhauser tri powers. All else being o.k., they will likely perform about the same as an early (55-56) 4 Bbl setup. Testing has shown that intake design  trails all the other 3 carb Y-Blk intakes of that period..

Manifold vacuum should work fine for the distributor.  It only requires a little bit of a different tune than ported vacuum.

Thanks for the input guys!
