  1. 84 with crate 350 - carb / fuel / emissions issues

    Engine Topics
    I have an 84 that the engine was swapped out to a 350 crate before I got it. Noticed lower fuel mileage lately and now hard starting when cold. Choke seems to be closed but it still struggles. Once it is warmed up it starts fine but I have noticed the mileage is off about 15%. About 3 months...
