I went from CIS to Weber 40IDA's on my 3.0 litre engined '74 Carrera and couldn't be happier. You will need to dyno tune your engine after going to Webers. I found around 25hp with Webers, headers and 2 in 2 out exhaust. My car has to be road legal but is basically a full on track car but is very drivable on the road. I still have the stock SC cams and pistons which will go when I freshen the engine. Go for it!
