There may be a thread on this.... but I can't find exactly what I'm after... I have an 01 with a factory modular 4.6 with stock pi heads.... are there any heads from 94-04 that might be a better power or camshaft option? Or am I better off getting my stock heads machined? The car has the original motor and only 88k on it. What is the statstics kn the tranny and notor issues from 88k and up? Are there any major issues to look for? What is the motors horsee power and tq peak ammounts in facroy rods.. pistons and seals?
