Edelbrock Thunder series 800 on 408 stroker???

I would opt for the Quick Fuel 800 or even a "little" 750. I'm running one on my 390 with a big *** cam, and it has street manners along with running right on the big end. It's not overly rich either.

They are infinitely adjustable, come with sight glasses to set the bowl levels, and have all the bells and whistles already there. 4 corner idle adjustment is a great option to have when you're dialing things in.
