I would like to replace intake with 4 bl. carb and remove lean burn system. Looking for intake that still allows the use of A/C. Some intakes say there is interfearence with factory A/C. Car is 87 5th with 318. What manifold did you use?
I use an Edelbrock Performer and am still able to use the AC pump. I think thats about the only aftermarket manifold currently available that will let you do so because the thermostat housing is offset to the driver side and there are bosses on the manifold to allow you to use the stock brackets. I also ran an Edelbrock SP2P 4bbl manifold that let me do the same, but those are no longer available new and are hard to find used.
