Whatever you do keep the quadrajet, a lot of people out there just toss them aside but they are great carbs for everyday drivers and fuel economy the front 2 bores are tiny and the back 2 are monsters as long as you keep your foot out of it and keep the secondaries closed you will get awesome mileage for the truck. changing the jets from stock may be a mistake. too small and the back bores may need to open sooner. Just play with the a/f screw if you think you can lean it make sure you keep a close eye on the temp gauge and look at your plugs listen for detonation and pinging.

My opinion get it running perfect in stock form a new coil set of wires cap rotor and pl ugs change the oil maybe drop the rear diff cover and fill back up with synthetic oil. then after that is done tweak the a/f on the carb next swap clutch fan for electric.

good luck looking forward to see how you make out I dig 70's GM trucks I restored or should I say fixed up 3 of them in past I sold my last one 4 years ago a 1978 chevy with a straight 6 2 bbl carb and 3 speed on the column. All the p/u trucks I had were column shift.
