Off road carbs

Evening peeps.

Recently been given a edelbrok 1825 650 thunder 4bbl carb, planning on running it on my '70 318 dart along with a performer intake. To replace the old carter carb job and standard intake that's on there now.

Was doing some research about it and keep seeing that it's an 'off road' carb?

Any idea what exactly that is?!

Can't see any reason why you couldn't street it so just wondering what the difference are.

Thanks
