[QUOTE="Tirefryr, post: 1413476, member: 550281"] The 5.0 had forged pistons until 92. Rods and crank were cast. The 4.6 has very weak internals. The con-rods are powder cracked in fact. Pull the rods out and you'll see the cracks for the main caps. No machining. Cheap ol bastids. The Cobra crank is nodular iron though. Surprisingly, they hold up well to power given a good tune. Near or past 500HP and you're asking for trouble. FYI, I have seen some very good drivers getting the later PI head and intake cars (99-04) into the high 13s stock. No way in hell your car is going to do any better than a 13.5 if you hook up and are a great driver. My Cobra's best stock form was 13.8 with limited traction. 60' times were dismal 2.30-2.50s. Horrible at best. Even with traction, there's just not enough power there and we all knwo how fat they are from the factory. [/QUOTE]
