I was told that before I add another Carb, that I should check to see how much vacuum it is pulling at, say, 50 mph.
I have a stock 235, with a Rot-chester Carb. But, I have an Edmunds 2 Carb Intake that I can put on the truck, IF it would give it a little more horsepower.
I want it to be a little stronger going up hills at 50 mph and not keep 'fading'.
Anyway, I was told it needs to pull about 2-3 inches at 50 or it would not help.
Is this the way to check?
