How to Build Max-Performance Hemi Engines details how to extract more horsepower out of your second-generation Hemi engine.

All the block options from street versus race, new versus old, and iron versus aluminum are presented. The book also provides full detailed coverage on the reciprocating assembly and gives special treatment to heads due to their essential role in flowing fuel and producing maximum horsepower.

Author Richard Nedbal explores major head types, rocker-arm systems, head machining and prep, valves, springs, seats, porting quench control, and much more.

All camshaft considerations are discussed as well, so you can select the best specification for your engine build.

Induction options including EFI, aftermarket ignitions systems, high performance oiling systems, and cooling systems are also covered.

The book also examines in detail how to install and set up power adders such as nitrous oxide, superchargers, and turbochargers.
