I bought a year ago my Pantera and realized only after the purchase that there is not the original engine installed. I contacted the previous owner who wrote me the following: "I do remember that the motor is what they called a Brute Force with Ford Racing SVO "Nascar" heads. It has a high dollar crankshaft and I believe Eagle Rods and JE Pistons." He also told me that the engine was installed by Hall Pantera in 1989. Does this tell you anything? I have also added a photo from the engine.
Thanks and brgds
