Im building a Pontiac 455, 30 over forged flat top pistons, #13 factory heads (72cc) Comps XE284H cam, its in a 77 T/A I have the W72 shaker scoop, carb is a 800 cfm Rochester Quadrajet #17057266. I figured the engine would be a small pain to start and keep running at first when cold. I plan on driving the car in the winter months too, just not when the roads are bad. It gets down to -20/-30 here in the winter nights, 0 to 20 during the day (Preston Idaho ) I read here somewhere of a Guy who has the choke removed and the post says the car starts right up and idles good while cold, not saying mine would, but as cold as it gets here, removing the choke may not be worth it. But its easy to reinstall if needed, either way if the choke is needed it will be converted to electric choke so the vacume hole to the choke housing will need plugged.
