Hello everyone I'm new to this site. I just purchased a 97 gt 5spd. Need advice in adding more reliable power. I have built a few fox body 5.0'S, but im new to the 4.6. The car has 91k miles on it with the current mods h pipe with mac cat back exhaust, king cobra clutch and k&n air filter. I want to boost the power up to around 300hp for starters and need advice on how safely. 1st off I need to replace that crappy plastic manifold that is cracked and started to leak coolant. everything else mechanically is great no other leaks or issues. Any advice would be great.
