How much boost can a stock '93 5.0 H.O. Engine Take?

I was wondering what the largest amount of supercharged boost my car could handle without doing many modifications, damaging it, or causing premature wear. I figured around 5-7 PSI. Thanks.

The information that I have gathered has told me that a stock motor should be able to handle 6 psi all day long.

Would my stock fuel system be sufficient, or would I need new injectors and fuel pump to run 6-7 PSI?

You will be able to run 8 psi safely if its tuned right, and only 8 psi because of your hyperutectic pistons. You should definitly upgrade your fuel pump. You can find a 255lph for around 120 bucks. As far as your injectors go, I really can't say. The stockers are good for around 300 horsepower and thats about what you will be pushing with the stock motor and supercharger. Check around on some supercharger kits. I think some come with all the stuff you will need.

Do you have any recommendations on what supercharger to get?
