just recently from the ford dealership I work at. I got a scraped 01' longblock from an escape. The motors hydrolcoked, but with the right materials I'll get it back together. Any sugestions, of where to start. I dont have the pcm, or any accociated wiring. so this means I got to use the heads, cams, valvetrain, pcm, upper, lower intake manifolds from my svt. Has any one done this? What is the compresion ratio, due to the 2.5 heads? Any advice befor i get started would be nice.
