i'm about to swap my 305 with a 383, do i need to buy new injectors, or will the stock ones work fine. the 383 isn't all high performace cause i can't afford it, so it just basically a stock 383 with a performance cam, so that's why i figured the stock injectors would work, but i'm not sure, thanks for all your help

 

Yes, you will definitely need different injectors. Your current injectors feed the correct amount of fuel for a 305; the 383 will require approximately 25% more fuel at all times, since it is also ingesting about 25% more air. 24 lb/hr injectors should be just about right.
