The engine will sit down in the rear when mounted in the chassis so carb will be near level. Not to worry anyway as cars/trucks seemed to work okay in San Francisco where they were just about never on the level and run quite well in the movie "Bullet" chase scene. The smallest Edelbrock carb is a 500cfm which is way larger than a 235 needs and you have no heat to the carb which is a pain in cold weather and at the gas pump. Holley makes a 385cfm 4bbl and Ford has a hot water heated car base plate with that bolt pattern. My word is not from the alter and some have 4bbl 235's that run good so just try and learn along the way. Good luck.
