Looking to upgrade that ailing mill in your 4x4? Thinking a spankin'-new crate engine might do the trick? When you're ready to up the ante, CarTech can help, with its newly revised High-Performance Crate Motor Buyer's Guide by John Baechtel. The hard-bound 128-page book details the available crate-motor options from GM, Ford, and MOPAR, in addition to those offered by aftermarket manufacturers such as Edelbrock, TA Performance, Scoggin-Dickey, and AutoCenter. The book also includes sections designed to walk you through a crate-motor swap, with chapters such as Prepping Your Crate Motor and Crate Motor Accessories. An appendix is also offered, which details popular engine dimensions, state emissions programs, and an aftermarket engine builder's source guide. If an engine swap is in your future, CarTech can assist you in the adventure. CarTech also offers a full series of automobile how-to and performance books, in addition to automotive history and personality publications.
