One is a manual choke while the other is electric.

The 3310 is your typical classic 750, the other is a newer model I believe. Why don't you visit Holleys site to learn more, and maybe even contact them if you don't find what you want to hear.

The 80508 has a ford kickdown linkage too. It would still work on a Chev just fine. They list the years because that was it's original application.
The 80508 gives you the electric choke (a $40 part) for $18. That's a good deal in my book. Take a look at the Holley site for the stock jetting on both carbs. You will probably need to lean out either of these carbs a little for your 350.
