-
Features - Revised, updated and enlarged edition of a best-seller from the SpeedPro series. - Ford's adaptable and tough SOHC engine is still a hugely popular for high performance applications, here is the tuning Bible. - The author is an engineer with much professional experience of building race engines: all the information is based on practical experience. - Suitable for the enthusiast as well as the more experienced mechanic.
Description Build a reliable, high-performance 1600/1800/2000 ‘Pinto’ engine for road/track, using many stock parts. Covers Cosworth versions of Pinto engines, too, and fitting Cosworth cylinder heads to Pinto blocks.
Synopsis Expert practical advice from an experienced race engine builder on how to build a high-performance version of Ford's naturally aspirated 4-cylinder 1600, 1800 & 2000cc Pinto engine which has been used in Ford's most popular cars (Escort, Capri, Cortina & Sierra - Ford/Mercury Capri, Pinto, Bobcat in USA) over many years. Whether the reader wants a fast road car or to go racing, Des explains, without using technical jargon, just how to build a reliable high-power engine using as many stock parts as possible and without wasting money on parts and modifications that don't work.
Also covers Cosworth versions of Pinto engines and fitting Cosworth heads to Pinto blocks. Does not cover 1300, E-Max 1600 or American-built 2300. | Table of Contents Introduction 7
