The '67-9 small blocks (273, 318, 340) without A/C all used the same pulleys and brackets on cars with the same options. Just use them as a set....you can't mix and match with '66 and earlier or '70 and later. There are many A/C setups but there again, whichever year you use, get all the brackets and pulleys off the same engine so everything will line up. The advantage of the '67-9 is that they are fairly easy to find and you can get the Saginaw pump those years and use the smaller diameter return hose. The '66 and earlier are all Federal pumps with the hard to find large return hose. If you run across a complete '70-up setup, by all means go ahead and use it but keep in mind the it makes it a bit harder to see the timing marks unless you re-degree your balancer and pointer to the other side. You'll have to redesign your radiator no matter which setup you use. The factory /6 had a curved lower hose connection so none of the stock V8 lower hoses will fit right anyway. Just have your radiator guy pull the tanks, rod and repair as necessary, and install the correct hose nipple where ever you need it to use a stock hose.
