Re: My first CVPI
A mild 5.4 with Trick Flow heads,cams and throttle body is good for an additional 100-110 HP and 130 ft. lbs of torque over a stock 4.6. It will also get over 22 MPG with stock 3:23 rear gears, but will require premium fuel with the small cc heads. Your driveline should be in like new condition, mod the trans for more fluid flow (NOT higher line pressure!) and softer accumulator springs for quicker shifts, and you will absolutely have a sleeper that will embarrass a lot of European iron. The cost is the downside, about $5,000 if you do the work yourself, but worth every penny in grins!
