Build approval someone please! August 24, 2019, 01:14:09 PM Hey guys I’ve been preparing to take my engine out to address rear main seal issue. So while it’s out I plan to do some mods. I been researching this for sometime now. Like everyone else I want to do it on a small budget. I feel good about my plan but I want to post it for some feed back. Now for the plan, my goal is 300whp daily driver. Parts: -1995 explorer GT40P heads, upper and lower intake, fuel injectors, and throttle body-New lifters-1.7 rocker arms-New push rods-springs-ford racing e303 cam-88 mustang ECUMy research tells me that this combination of parts can potentially yield me the desired hp I seek. Please any feedback will be much appreciated. Disclaimer I am a complete novelist when it comes to engine building. This will be my first engine build.
