I run a racer Brown 242 @ 50 and 510 lift. My buddy runs the identical comp that you have, and runs about 1 tenth faster in car that's 100 pounds lighter. 9.6:1 440 with eddy heads. Import to realize that a good base engine. (cubes, heads, cam, etc) will only get you part way there. tune(timning, carb mix, and setting) gear, tire, etc.. is just as much part of getting it there.

A 850 Mighty Demon probably flows 950cfm. You are going to need at least 950 for that engine.
I run a manual six pack that flows about that much and it is just about right for my "small" 440 that only runs high 11s in a 3950lb car.
See what your manifold vacuum is when you pick a carb. Any more than 2 inches of vac at WOT and the carb is probably too small for drag racing.
Dougs Headers are 2" primary and 3.5" collector. They are more like the size you need.

Because running a Mopar in the UK is getting TOO expensive!!

I'm running a 416 stroker. I've tried a lot of carbs over the years. But my Quick Fuel 950 gives it just what it needs. My vote the 950.
He needs a carb that will truely flow 950-1000 cfm, a 950hp won't do it, all it is is a opened up 750dp, might work great on a stroked SB, but a stroked BB pushing 500 cubes needs decent CFM, not knocking the 950hp, its a great carb, but not for a combo like that if your after full potential. Thats why i recammemded either the 1000hp or 850 mighty demon, the 1000hp is a spiffied up 850dp, both these carbs flow well into the 900 cfm range. I had a fairly mild 446 with iron heads, it screamed with a set of 2" hooker headers & an 850dp, he has way more then that, plus its a stick car.
