The '87 Crown Vic only puts out around 130 hp, right? Well I would like to change that. I have the engine, I figure I could stroke it into a 347, change out the air density sensor to a mass air, put better heads on like gt-40's maybe, replace the cam shaft, and the intake. How much of a difference would that make? Any rough estimate on how much it will cost? (should I even touch the pistons? And what about a super charger?)
