Which carb Would be better?

[BillaMustang]

I currently have a 750 Speed Demon carb.

But was thinking of getting my Holley 700DP back And putting a Pro-Form main body on it.

BG says that the speed demons are for cams up to [email protected] so what happens if you run a cam that's 247 and [email protected]

Combo is
331 with 10.4comp.
AFR 185's
VictorJR intake
Custom FTI cam
Bassani LT's
Full MSD and all the bolt on's etc..
It's a stick car with a 4.30 gear and 26 inch slick's.

So is there anyone in the High 10's with a 750 Speed Demon?

You can run whatever carbed you want but you want to make sure you have the right power valve for your setup. Too much duration wont create enough vacuum at low engine speed and so your power valve wont work correctly, so maybe changing valves could make your Demon run fine. Either way, they are great carbs.
