I am almost 100% certain that the carb you posted is the same one that I used but you might want to wait for somebody else to chime in before you pull the trigger.

The installation was very easy - I even helped. We had done an engine swap from a '66 to my '64 and added the Holley a few months later. The adapter is required and you may have to purchase a different return spring and perhaps tweak the rod coming from the accelerator linkage. In my case I think we added a different return spring mounting "bar" so the spring would not interfere with the larger carb.

Ive attached a before and after. Sorry the images are so small. I hope they help.
