A simple question, but not necessarily a simple answer. There's a lot of things to consider such as hood clearance, mixture distribution, throttle linkage, etc. etc. etc., but the short answer is, yes, it will work on a spreadbore intake, & yes, there are adapters available. I assume you are installing the E-brock on a stock intake; you might also look at the Holley 650 & 800 Vacuum secondary spreadbores, if you plan to keep this intake permanently. Also, make sure your throttle/trans linkage doesn't bind & is able to open the carb all the way at full pedal travel. Good luck & welcome to the board!

Holley used to make a square bore to spread bore adapter plate. If they don't still make them you could probably pick one up at a swap meet or on ebay.

Mr. Gasket used too (probably still do also) make one that you could use to install a square on a spread. They ran about $15 or so at Autozone and such
