Customer Reviews

Covers a little about alot....3
Lots of good general information about building a strong XK engine, but unfortunately doesn't really give you an idea on the sort of improvement you could expect from the modifications suggested. Anybody who is used to tuning books by the likes of David Vizard will be disappointed as there isn't any flow graphs, dyno results, comparison tables etc. to back up any of the modifications recommended.

A fair portion of the book also deals with general engine building techniques such as how to measure big end bearing and piston to bore clearances etc.

I would recommend this book to someone who was just looking for some general info on early Jag engines, but it is unlikely it will provide you with enough information to get the best from your engine without a lot of outside help.

For me it has raised more questions than it answered.

It does what it says on the tin.4
I am about to rebuild the engine in my 1967 S-Type. So I wanted to know what to do to make sure its running within reason to the best of its ability.
This book is full of things to do that are more appropriate to high reving racing engines, rather than fast road.
Its worth a read, and I paid somewhat less than the insane £22 some sellers are asking.

This book will tell you that for anything other than full out racing, don't change the carbs (1" and ¾ is fine). Don't change the valve size, don't change the cams. You don't need forged pistons or con rods! -Unless you are going to run it at 6000 RPM.... 6000 - are you mad!!!!!

So I guess in a lot of respects this book has saved me money! -On expensive machine shop work I just don't need!

Think of this book as a Haynes manual. Its not as specific as it could be but its worth having if you can get it for about £10ish.
