I've been thinking of upgrading my 1600 in my 72 van for a while now and a GE coded engine has become available to me (also has a CE coded engine, 1700??), just looking to get an idea of what would be needed. I know I will need a new gearbox as the 1600 one won't work well (though on looking I think the CE engine would work ok with my 1600 CE coded box). If I wanted to go injection i'd need to modify the fuel tank, can I still use the old one or would I need a compatible one? I may just keep it non injection and just run normal carbs, i'm guessing this is possible. Am looking to convert/upgrade to have a little more power and more reliability.
