I'm there with you on the budget build. Except we are building ours a little out of sequence! I'm doing paint last!
I had a Weber 45 DCOE sidedraft with the RB intake manifolds that was going to go on it, but I swapped with a local guy for the Holley kit instead. 4 barrels offer a little better driveability from what I hear. jfaplanet has the Dellorto 48 on his REPU and it works well with his set up. Most guys around here run the Holley kits, so that is why I am going that route. Don't forget that with the Dell, you also need an upper manifold.
Which Carter pump did you get? You will also need a regulator for either carb you pick.
Are you going to DGRR with this? We can compare once we are there
