Injection with an aftermarket ECU controlling ignition too will give more power than carbies any day. I am running limited budget and love the old style stuff as that's what I worked on as a mechanic back in the day. If you look at the actual valve seat diameter on early 1.7's and 1.5's its actually 32mm which is the choke size on 36idf so IMO 40's won't do much even at high revs, in fact they may even cause a pulse back up the carby when the flow hits the valve seat; of course if you increase valve size the 40's are viable. Plus with race cams the 36's should get me a bit of lowere end torque. I am getting the injector cutouts welded out of my 1.7 i.e. heads before finishing the polishing
