Advice on 4.6 500hp build.
Hello everyone I’m looking for some advice. I have a 96 mustang gt that I built a couple years ago. It has forged pistons and rods, stage two cylinder heads by mhs and stage three camshafts. The car makes 290hp to the wheels at a 10:3:1 compression ratio and is mated to a 4r70w transmission with an fti 3400 converter. I’ve reached a point where I want more hp but my question is do I spend the money to upgrade what I have which would involve a forged crank, different pistons to lower the compression ratio, and a supercharger with appropriate camshaft. Or do I simply try to sell my car and start anew with a cobra mustang with a 4.6 dohc engine n/a. I don’t have the money to try and find a 03/04 termi. Overall my goal is 500 hp to the wheels. Let me know what people’s thoughts are and thank you. Also if anyone has any advice on things to avoid it would be useful, ive heard there were some problems with the 4.6 4v 99-01 heads.

you can still boost the motor you have. not sure of the specs of the cams but either way if you spec'd the rods/pistons appropriately i couple pounds of boost should get you to your power level. Dont fear the compression. A good tuner and good gas you should have nothing to worry about

Yeah you should be fine as-is. Throw a centri and fuel mods at it, your compression is a hair on the high side but any competent tuner should be able to make it run at the power level you want on pump gas, safely. Your cast crank is good for well past the hp level you're proposing.
