I agree with +8Rich. I have just converted My +8 from a Carb to FI. I now wonder why???? I also have a 1963 +4-4Str that I have driven many miles in the U.S. and even Northern Europe. The SU's have been faultless and easy to keep up to snuff. The ignition is simple and within My capability to maintain/repair. It is more comfortable, reliable, and handles better than My +8. No it does not go from 0 to 60 faster than My +8. But that is the only thing it does not do.
