Hello Guy and thank you for responding to my question. I understand what you say about your own installation, using more modern techniques also assists in obtaining more power from the given engine.
Just as a small matter of interest, and I understand that my own car is insignificant to the topics displayed here on your web site, I have a 1973 Simca 1501 into which I have installed a Fiat 2 litre unit with twin 40 Dellortos, 132 5 speed gearbox and rear axle from an '81 Argenta. This was nearly 15 years ago but I still have the car and I suppose it is quite a rare machine. Because it is a fairly light weight car to begin with, the extra power does make alot of difference as you will understand.
Since I was a teenager (1960's) I have always been interested in the Fiat/Alfa/Lancia twin cam unit and the rare Abarth power units and cars to which these units were fitted. I came across your abarth-gmr.be site because of a link mentioned in my club newsletter. What an interesting web site it is!
My best wishes to you, your team and all enthusiasts.
