Not much more info,i've been slacking on keeping my Flickr page up to date.
I know what you mean about 'limited budget' though.
Due to some bad advice and workmanship (not from here I might add!) i've basically had to re-do my front and rear suspension which hurt my budget somewhat.
I've still got bodywork to attend to if I could stop driving it!
The main 'issue' you will find with fitting the V8 and stock steering is probably header/exhaust to steering clearance.
I'm running a MII IFS so that doesn't really relate to yours,the guys in the Hi-Po section will keep you right though. (Use the search function and i'm sure you'll find the info you need)
The 10 bolt rear's a good choice though,nice width and better ratio,I assume you'll be changing the front to discs (worthwhile) or else you'll have to run 2 different wheel bolt patterns.
