What Carb Size

[69Chrgr]

Hey Guys. Another question for the experts. Finsishing up the install on my new 408 small block. I have a 750 mechanical secondary Demon on there now, however I am looking at some Quick Fuel carbs. Can anyone give me some suggestion on size and model? Here is my combo:
68 Cuda
408
Stock Eddy Heads
Hughes Roller 242 and 246 duration @ .050 lift w/matching valve springs
.555 and .565 gross lift
1.6 rollers
Forged Flat Tops
Approximately 11 to 1 comp.
Mech. Fuel pump
Dynamic 3800 Stall
Reverse Manual Valve Body
3.91 Gears

Hoping to notice a difference from the old 380 horse crate motor. I currently have a 750 mech. Demon that I'm going to sell to a Chevy friend, as I think he needs all the help he can get.
Thanks as Always,
Darren

What intake manifold are your using ? I understand single planes need a smaller carb than dual planes.

Your probabley OK with your 750 and I think that your buddy could use your old 380 crate more than your carb.

Oh yeah, sorry about that. It's an M1 Single plane off the old crate motor.

Could you tell me about your combination 340? I really appreciate all of the feedback from everyone. Thanks again from Midlothian, Tx.

I think the 750 Demon would do well. If your on the strip more than the street, stepping up would be fine.
