Weber Marelli Fuel Injectors ??????

my mate wonts to put some greys in his escort cosworth ( and yes i no i asked a very simler qwesten last week ) will these work ok in a escort cosworth and we have been told to put blacks in but it all down to $$$$$$$$

Weber Marelli Fuel Injectors Labelled IW-043

I removed these injectors from my 1992 Chevrolet Corvette but I am 100% certain that these are not originally from my car. I removed them as the other 4 injectors were the original correct ones for my Corvette, so I decided to look for some new ones that all matched up.
These Webers are undoubtedly the wrong flow rating for my car - which is meant to run 22 lb/hr injectors at 3 bar (43.5 psi) - which I believe is around 230 cc/min. Unfortunately I cannot find any information on what these IW-043 injectors actually flow. I have looked on a few websites and I can find informtaion for the following:
IW031 270 cc/min
IW042 190 cc/min
So you could make an educated guess what these run - although I did read on some other sites that these could be over 300 cc/min -

Phone webcon and ask for Andy Gray, he will sort the spec out, I don't have details on these to hand.

as i said before, any injector if it physically fits the manifold will work...

but you need to find SOFTWARE to run them...do you think any tuner is going to have a file written and tested for injectors from someones corvette, that were already used before hand probably 30years ago?
