I think the question relating to carbs does belong here.Cobalt,Im certainly not arguing with you as you know the respect I have for your knowledge.
Its just that my opinion is: The carb fits the engine not the gear ratio. The engine is built for a purpose and the driveline is built for a purpose,not because of the others parts short comings.
good example is myself; I use a 3.50 gear ratio because that is what the car needs to perform what I want(not drag racing) My engine has a big cam that a lot of people would say"you should have 4.56 gears for that cam"
4.56 gears would not suit my purpose at all.
so I say,imo,a 750 ish cfm carb is a good choice for that engine.
Will that truck make a fast pass at the drags?
