Must-Have Book for Mod-Motor Fans

If you like hundreds of pages of dyno tests with before and after comparisons, then you have to add this new book to your library. Building 4.6/5.4L Ford Horsepower on the Dyno is written by Richard Holdener, the dyno guru who also brought you 5.0L Dyno Tests )

Building 4.6/5.4L Ford Horsepower on the Dyno takes the guesswork out of modification and parts selection by showing you the types of horsepower and torque gains expected by each modification. The book features over 200 pages, 340 photos and 185 back-to-back dyno graphs to show you which parts increase horsepower and torque, and which parts don’t deliver on their promises. Unlike sources that only give you peak numbers and gains, Building 4.6/5.4L Ford Horsepower on the Dyno includes complete before-and-after dyno graphs, so you can see where in the RPM range these parts make (or lose) the most horsepower and torque. Holdener covers upgrades for 2, 3, and 4-valve modular engines, with chapters on throttle bodies and inlet elbows, intake manifolds, cylinder heads, camshafts, nitrous oxide, supercharging, turbocharging, headers, exhaust systems, and complete engine buildups.

At just $15.72 the book is about as good of a deal as subscribing to FordMuscle!
