I searched through a few threads but couldn't find an answer. I have a stock 1991 5.0 and would like to upgrade it and get a better sound and performance out of it. I did some research on YouTube and I love the sound of the Bcam with BBK shorty headers, H-pipe and Flowmaster mufflers. I would not be doing the work myself, but are there any other modifications that must be done to the internals of the motor when swapping a cam out? GT40 heads seem to be popular but I can't find any at a reasonable price. Thank you for any input.
