right just to add since i sourced these springs through joe iv just asked him what they are and so you all know im not talking shit they are from an old cosworth dfr or dfv i think he said so are actualy f1 valve springs so i was wrong to quote f1 spec but didnt want to say untill i was sure...you can all take the piss as your all so knowledgeable but havent even heard of a f1 valve spring being fitted to a yb from an engine of the same era..i was going to use these springs as weve used them in a few fancy engines and know they work well....but hey you lot know better and find it funny to take the piss when infact we are using f1 springs!!!!
also chip you know it all iv actualy been present when joe has taken apart and rebuilt v10 f1 engines as late as a 2007!!!why do you feel the need to comment on someones abality when you know fuck all about them????
joe has been flown out all over the world to sort certain f1 cars be it not a current 2009 but say 2 year old one..
just because you might not have the knowledge (or even anyone you know)to build an f1 engine doesnt mean that others havent!!!
