I have just reread my Rover V8 books by David Hardcstle about performance tuning the Rover V8. Many of the parts are available in the UK, but I can't find them in the USA. Such as Crane roller rockers and such.
Can a screamin demon be made out of a 4.6 long block and a hot cam, or are big valve heads required?
I would like to find out who could build a Rover V8 for me at a reasonable price.
