any 1 read the book or tryed any of the stuff??

in"how to modify ford sohc engines" by david vizard

read a few bits but theres a lot to go through,reckon its easier to look on chrisg web site.

just thought i'd get it cos i have to have somethin techy sittin in my car (to read at t-break)

the thing got me was the bit bout makin inlet ports smaller a lot of the race pintos i have seen have them the size of a pint glass

I haven't read this book but I'm familiar with David Vizard's work know it to be generally excellent.

About the port size, the first question any tuner has to ask is 'what purpose will the engine be put?' i.e. race, road, mostly race and some road etc etc. If a fair proportion of road work is envisaged then wide airways will be a problem due to the low gas speeds at lower rpm which lead to poor cylinder filling and poor swirl which means low torque production.
