So i have this 3.4 engine block from a 94 camaro, i just got the aluminum heads, lower and upper intake from am 01 grand am gt. My problem now is that i chose this conversion because its a direct bolt in replacement to the 2.8 thats in my truck. i overlooked the fact that the 3.4, 3100, and 3400 series motors were never given an aftermarket carbed intake manifold. i have heard a few guys being able to modify the stock 3100/3400 upper intakes to facilitate a carb, but they have only mentioned it and never posted any pictures of the procedure. if anyone has any knowledge of this procedure or have any ideas please let me know. i want o have my truck ready by summer.
