950 Proform too big for 440?

[BB73Challenger]

OK, I know I was picking Chryco's brain about carb's yet AGAIN at Carlsile,
And I just want to make sure I'm not jumping in over my head with too much carb.
And MEK you just added a Proform 850 to your 440 and said it was great.

So, I would like to upgrade the cam and I now have a shot at a Proform 950 that is used.
Am I getting into too much carb?
I know CP you said you even ran a 850-950 up to 1050 with each step giving you more, but I just wanted to make sure my next leap would be what I wanted.

I know the 950 is chokeless, no problem.

Any feedback would be great, and it's getting to the point if I had .05 cents for everyone of my carb questions I would be a millionare.

Right now it's a 440 with all the typical upgrades - intake - headers - as said I would like to change cam and stock cast iron heads.

You have to start off with the premise that every carb is over-rated in the CFM it flows, because they are. Here's a good formula to use, that is if you trust the guy that does Billy Glidden's carbs. Don't remember the last time he lost a race.

, my call would be the 850 . but if I remember correctly you have headers & cam etc so if the deal is reasonable for the 950 I would go for it , it should work well
