I have a 95 GT/manual trans, 115K. It has the following mods: 355 gears, BBK cold air, BBK Ceramic shorty headers, Pypes X pipe, Tri X shifter, msd coil. I have picked up a 95 Cobra Upper and lower intake with tb. How long would it take to change out and would I need anything besides gaskets? Do you guys recommend doing anything else why I'm doing this? My engine bay is green, while the rest of car is white. I thought about pulling engine, painting engine bay, doing oil pan gasket, rear main, etc. What do you think?
