Thanks Rob & Matt. Originally I went down the single carb route because I thought it'd be a bit easier/cheaper as well as looking a bit more period under the bonnet. Have to say that I'm not too sure about that now though I've obviously started down the single carb route now though so I'll see it through to the end & I've heard good things about single carbs on Zetecs so hopefully the car will perform well. Having said that I doubt the car will ever be truly finished & I'll probably upgrade/change things later on. Space is quite tight between the engine & inner wing - not really enough room for twin sidedraught Weber 40's/45's - so bike carbs/throttle bodies might well be on the cards at a later stage.

Thanks again for the feedback - I'll try & remember to post any future updates
