Which Carb for a 318 with an LB4D intake?

Hi everyone, am getting my stock 318 rebuilt (I know, I know 318, really) but I want a daily driver with just a bit of power on a budget of course...

So after reading multiple post I decided to go with the LD4B intake with a Holley 570, but am not sure which model works best. Is it the Holley 4150? Electric or Manual Carb?

I apologize as I'm not really motor savy.

Oh, this is for a 74' Barracuda. Will also be doing headers and dual exhaust. Not sure what kind yet either.

Any help is greatly appreciated!!!
Thanks,
