Hi,
If you are working on a Fiat 1100 you should give Robert Rodgers at
Shade Tree Enginetrics a call at 972-771-0804. He prepares 1100's for
Wainers, Stangulinis, Bandinis, etc.. He prepares the motors for my H
Prod Fiat 850 and 2.0L Formula Abarth. He is great about offering
advice and you can also ship him stuff to work on and he will ship it
back. He has shipped stuff all over the world. He has had cars race in
the Milli Miglia and at Monteray. They have a WWW Page at:
