Carburetor/Intake Manifold

I'm getting ready to do some changes to my '70 C10, 350 5.7L V8. Adding a new carburetor (Holley 4776 double pumper, ACCEL shorty plugs 574S, and MSD 8.5 wires). Already running MSD 6AL setup, just upgrading plugs, time for new wires and my bothers who owns a '70, '70, and '69 C10 respectively have always insisted I change to a Holley. They run the 4776 and 4777 Holley carb and have been seeing better success than me. So I gave in to the change.

I have a Edelbrock #2701 Intake Manifold on it right now, running a 1406 600 EB carb.

Question: Will the Holley Carburetor fit on this bore Intake? I'm assuming it will, but before I take it apart Saturday I just wanted to make sure...

Thanks in advance for the advice.

Re: Carburetor/Intake Manifold

Is the 2701 the EPS intake? If so... the square bore holley will fit. The 4776 should be a 600cfm carb, which will be perfect. The DP is a little overkill for a street rig. It will like a vac sec carb like an 1850 better for DD use.

Re: Carburetor/Intake Manifold

Double pumpers are good for one thing....WOT, as in racing.
A vacuum secondary carburetor is much better suited to street driving.

^^^^What he said^^^^

Double pumpers are a BIG waste of gas on the street. Stick with a vac. secondary. You will be much happier.
