Truck is a 72. 250 cid 3 speed on the tree.
There has been no signs of HEi, but could have been in and out again.

Thanks for the input so far guys.

Poobably never had HEI. You might think about putting it on in the future. Great upgrade.

The TCSS is obsolete. Never did much good anyway.

Keeping the Idle Stop Solenoid is probably unnecessary, but don't throw out the stuff if you're going to run a Monojet. If it runs on after shutting the key off, you will want to put it back on. Also called an Anti Dieseling Solenoid.

If you're going to an aftermarket intake, 2- or 4-barrel carb and headers, then all this old wiring is obsolete.
